Graphics Card Guide
Your graphics card powers gaming visuals, 3D workloads, creative apps, and overall display performance.
When shopping for a GPU, it helps to understand the main families of graphics cards and why VRAM matters so much.
NVIDIA GeForce
A very popular option for gaming and creator builds, known for strong performance across many price levels.
AMD Radeon
Often a strong value choice for gamers who want solid raster performance and competitive price-to-performance.
Intel Arc
A newer desktop GPU option that can be appealing for entry-level to mid-range users depending on their needs and budget.
Why VRAM Matters
VRAM stores textures, frame data, and visual assets. More VRAM can help with higher resolutions, larger textures, and modern games.
Gaming Performance
Your GPU has a major impact on frame rate, visual settings, and how smooth games feel.
VRAM
More VRAM helps when running higher resolutions, texture-heavy games, and demanding creative tasks.
Resolution
1080p usually needs less GPU power than 1440p or 4K, so your target resolution matters a lot.
Power & Fit
Always check PSU wattage, case clearance, and connector needs before choosing a larger graphics card.
What VRAM Actually Does
How much do you need?
- 8GBEntry level1080p gaming at sensible settings. Getting tight in the newest games with textures turned up.
- 12GBThe sweet spotComfortable at 1440p with high textures, and enough headroom for ray tracing at that resolution.
- 16GB and upHigh end4K with textures turned up, ray tracing and frame generation, video editing, 3D and local AI work.
Capacity is not the same as speed — a card with plenty of memory and a slow processor on it is still a slow card. And how much you need depends on the resolution you play at, the settings you use and whether you turn on ray tracing.
VRAM Stores Visual Data
Think of VRAM like fast memory dedicated to graphics. It holds textures, frame buffers, and other visual assets close to the GPU.
GPU Uses It in Real Time
If a game needs more visual memory than the card has available, you may see lower settings, stutter, or reduced performance.
Choosing the Right GPU
Great for mainstream gaming
For many users, a modest to mid-range card is plenty for smooth 1080p gaming and everyday PC use.
A strong sweet spot
1440p usually benefits from more GPU power and healthy VRAM, especially if you want higher settings and frame rates.
Most demanding tier
4K gaming typically needs a stronger graphics card and more VRAM because the GPU must push far more pixels and larger assets.
Reading a graphics card’s spec sheet
Every card is described by the same handful of numbers, and none of them mean much until somebody explains what is being measured. This walkthrough takes the spec sheet a line at a time, which is the quickest way to stop guessing at model names and start comparing like with like.
- What the GPU actually is, and why the chip — not the brand printed on the cooler — does the work
- What VRAM is for, and why more of it does not by itself make a card faster. The capacities listed further up this page are the practical version of this
- Memory bandwidth and bus width: how fast data moves, which is a separate question from how much the card can hold
- Clock speeds, and why two cards built on the same chip can differ a little without differing a lot
Common graphics card issues, and how to fix them
The five problems our PC Support team sees most with graphics cards, and the checks that resolve them. The most common of all is simply the monitor cable being in the wrong socket.
Core Concepts
The five things that matter most when choosing a graphics card.
- Start from your display1080p high-refresh, 1440p, and 4K demand very different performance. Pick your resolution and refresh target first, then choose a card that can drive it.
- VRAM8GB is a reasonable minimum at 1080p; 12–16GB is the safer target for 1440p, 4K, high-resolution textures, and ray tracing.
- Ports and connectivityCheck the output types and counts against your monitors — DisplayPort is usually best for high refresh on a PC, and HDMI 2.1 handles 4K at high frame rates.
- Fit and powerConfirm card length and slot thickness against your case, then check your PSU wattage and that you have the right native connectors rather than chained adapters.
- Ray tracing and upscalingRay tracing costs performance; DLSS, FSR, and XeSS recover most of it by rendering lower and scaling up with little visible loss.
What Customers Ask Us
Five questions our PC Support team is asked most about this. Tap any one to open it.
How much video memory do I actually need?
It depends on resolution and settings more than on the card’s name. As a rough guide, 8GB is workable at 1080p and is getting tight in the newest games at high textures; 12GB is comfortable at 1440p; 16GB or more suits 4K, ray tracing and creative work. Capacity is not the same as speed, though: a card with lots of memory and a slow processor on it will still be slow. Treat video memory as one figure among several rather than the headline.
Will a new card fit my case, and do I need a new power supply?
Two measurements decide the fit: the card’s length against the clearance your case lists, and its thickness in slots, since many cards occupy two or three. Both numbers are on the product page. For power, check the card maker’s recommended supply wattage and the specific connectors it needs — and give it cables running separately back to the supply rather than splitting one. If your supply is close to the recommendation, that is where crashes under load tend to come from.
What do Ti, Super, XT and XTX actually mean?
They are tier markers within one generation, not separate technologies. On NVIDIA, plain sits below Super, which sits below Ti, and a Ti Super sits above both — each step usually adding cores, memory bandwidth or both. On AMD, XT is above the plain model and XTX above that. The important habit is comparing within a generation: a newer generation at a lower tier often beats an older generation at a higher one, so the suffix alone tells you little across generations.
What are DLSS, FSR and XeSS, and should I use them?
All three render the game at a lower resolution and use the card to scale it back up, which usually gains a lot of performance for a small loss in sharpness. DLSS is NVIDIA’s, FSR is AMD’s and works across brands, XeSS is Intel’s. Newer versions look better than earlier ones, and at higher output resolutions the compromise is less visible. They are generally worth turning on, particularly at 1440p and 4K — and the quality preset matters, so try the highest-quality setting first.
Should I remove my old drivers before installing a new card?
A clean install is the safer route, especially when switching between brands. The current driver installers from NVIDIA, AMD and Intel all offer a clean-install option that removes the previous version first, and that is usually enough. Mixed-up driver files are a genuine cause of crashes and of Windows falling back to a basic display adapter. Download the driver from the card maker directly rather than relying on Windows Update, which often supplies an older build.

What AMD Radeon is best for
AMD sells its graphics cards as Radeon RX. It tends to win on value rather than on outright features:
AMD’s upscaling. It is open, so it also runs on NVIDIA and Intel cards and in far more games.
At most price points AMD gives you more video memory, which helps at high resolutions.
Adaptive sync that stops screen tearing, and free for monitor makers to use — so far more monitors support it.In plain terms: if you want the most raw gaming performance and memory for the money, and you are not chasing the very best ray tracing, Radeon is strong.
Which generation?
Radeon uses RX plus a four-digit number — an RX 7800 XT is a 7000-series card. Higher first digit means newer:
Suffixes: plain is the base card, XT is faster, XTX sits at the top, and GRE lands between plain and XT. Note AMD skipped RX 8000 on desktop — 6000, 7000, then 9000.
Workstation and AI cards
Not gaming cards. Here is what they are actually for:
CAD, engineering, broadcast
Workstation cards with certified drivers tested against professional software, plus more memory and error-correcting RAM.
Not faster for games — only worth it if your software requires certification.
Data-center AI and HPC
Server hardware for training large AI models, with huge memory and no display outputs.
Not for a desktop. For AI at home, a high-VRAM Radeon or GeForce card is the practical pick.
Short version: Radeon is the value play — more memory and more raster performance per dollar. Pick RX 9000 if ray tracing matters to you, RX 7000 if capacity and price do.
What Intel Arc is best for
Intel is the newest of the three, selling cards as Arc. It competes at the entry and mid range, and has one genuine standout feature:
Intel’s upscaling. It runs best on Arc but also works on other brands’ cards.
Arc usually includes more video memory than rivals at the same price — useful headroom on a budget build.
A strong AV1 hardware encoder, and the main reason people choose Arc for streaming and video work. How it compares depends on the software you use and the settings you pick.In plain terms: Arc is worth a look on a tight budget, and it is genuinely excellent for streaming and video work. On a modern system with Resizable BAR enabled it punches above its price.
Which generation?
Arc uses a letter for the generation and a number for the tier — an Arc B580 is a B-series card:
Two things to check before buying Arc: your motherboard must support Resizable BAR (most boards from 2020 on do, and it may need enabling in the BIOS), and very old games using older graphics APIs can still perform unevenly.
Professional cards and one caveat
What else carries the Arc name, and the one setting that matters most:
CAD and professional viewport work
Workstation versions with certified drivers and, on some models, far more memory than the gaming cards.
Not faster for games. Only relevant if your software asks for a certified card.
Required for full Arc performance
A motherboard setting that lets the CPU access all of the card’s memory at once. Arc depends on it more than other brands do.
With it switched off, an Arc card can lose a large share of its performance. Check the BIOS first.
Short version: Arc is a solid budget choice and often good value for streaming and video encoding — provided your board supports Resizable BAR.
What NVIDIA is best for
NVIDIA’s cards are sold as GeForce RTX. Three things are what you are really paying for:
Renders the game smaller, rebuilds it with AI. Big frame-rate gain, little quality loss.
Lighting and reflections calculated like real light. NVIDIA has generally led here, though the margin varies by generation and by game.
Editing, 3D and AI software is written for NVIDIA first, so it just works.Which generation?
The first two digits are the generation — an RTX 4070 is a 40 Series card. Pick one to see what it suits:
Within a generation the last digits are the tier — 50/60 entry, 70 mainstream, 80/90 high end. Ti or Super means a faster version of that number.
Workstation and AI cards
Not gaming cards. Buying one by mistake is expensive, so here is the short version:
CAD, engineering, medical, broadcast
Same chips as GeForce plus certified drivers for software like SolidWorks and Revit, more memory and error-correcting RAM.
Not faster for games — only worth it if your software requires certification.
Training and running large AI models
Server hardware with huge memory for datasets a normal card cannot hold. Many have no display outputs.
Not for a desktop. For AI at home, a high-VRAM GeForce card is the practical pick.
Short version: for gaming, streaming or creative work on a desktop, GeForce is the line to look at. Favour a newer generation over a higher model number in an older one, and treat VRAM as seriously as the name on the box.

No picture after installing the graphics card
Nearly always the monitor cable or the card not being fully seated. The card being faulty is the least likely explanation.
Usually one of these: the monitor is plugged into the motherboard rather than the card, the card is not fully clicked into its slot, or its power cables are not seated.
Try these in order
Before you open the case: shut the PC down, unplug the power cable, hold the power button for about ten seconds to discharge it, then touch a bare metal part of the case to ground yourself. Never open the power supply itself, and never test or probe anything while it is plugged in.
- Move the monitor cable to the card. With a separate graphics card fitted, the cable must go into the card at the bottom of the back panel — not the sockets built into the board above it. This is the most common cause by a wide margin.You should see: A picture appear straight away.
- Check the card’s power cables. Most cards need one or more cables from the power supply. Push each until it clicks; a partly seated connector looks fine and will not work.You should see: A click as each seats, and the card’s own lights come on if it has them.
- Reseat the card. Release the clip at the end of the slot, lift the card out, then press it back in evenly until the clip closes by itself.You should see: The clip close on its own and the board’s VGA debug light go out.
- Try the other sockets on the card. A card usually has several outputs. Try a different one, and a different cable if you have one.You should see: A picture on one of them, which identifies a faulty port or cable.

The screen goes black or the game crashes under load
Failing only under load points at power delivery or heat rather than the card itself. It is a common and usually fixable pattern.
Usually one of these: the power supply cannot meet the card’s peaks, a power cable is shared or daisy-chained, the card is overheating, or the driver install went wrong.
Try these in order
- Check each power cable runs separately to the supply. Give the card its own cables rather than splitting one with an adapter or a daisy chain where you can.You should see: Stability return under load.
- Watch the temperature while playing. Use the card maker’s tool or the Windows Game Bar. Note the peak rather than the resting figure.You should see: A peak that stays within the card’s normal range.
- Check the case has airflow. Air in at the front, out at the back. A card pressed against a front panel with no intake will get hot quickly.You should see: Lower peak temperatures once air can move.
- Reinstall the driver cleanly. Download the current driver from the card maker, choose the clean-install option, and let it remove the old one first.You should see: Crashes stop, if a mixed-up driver was the cause.
- Test at lower settings briefly. Drop the resolution or turn off ray tracing for a few minutes. If it holds up, the card was being pushed past what the power supply or cooling allows.You should see: A clear difference, which tells you where the limit is.

Windows is not using my new graphics card
If a system has both built-in graphics and a separate card, it can end up rendering on the wrong one — which feels exactly like the new card not working.
Usually one of these: the monitor is plugged into the motherboard, the driver has not installed, or Windows has assigned the game to the built-in graphics.
Try these in order
- Check where the monitor is plugged in. If the cable is in the motherboard, Windows will use the built-in graphics no matter what card is fitted.You should see: The card listed as the active adapter once the cable is moved.
- Check the card is recognised. Open Device Manager and look under Display adapters. Listed as “Microsoft Basic Display Adapter” means the driver is missing.You should see: Your card named properly.
- Install the driver from the maker. Download it from NVIDIA, AMD or Intel directly rather than relying on Windows Update.You should see: The card named correctly and its control panel available.
- Set the preferred graphics processor per app. In Windows Settings, Display, Graphics, add the game and set it to High performance.You should see: The game using the card rather than the built-in graphics.

My frame rate is much lower than I expected
Worth separating three things before assuming the card is at fault: what is actually limiting performance, whether the card is running at full speed, and what the settings are asking of it.
Usually one of these: the processor or memory being the real limit, a power setting, the resolution or ray tracing costing more than expected, or the monitor still set to a low refresh rate.
Try these in order
- Check which part is at its limit. While playing, watch graphics and processor usage. If the card sits near 100%, it is working as hard as it can and the settings are the lever.You should see: One of the two consistently near its ceiling.
- Check the monitor’s refresh rate is set. A high-refresh monitor often arrives running at 60Hz. Set it in Windows display settings.You should see: A higher figure available and selected.
- Enable the memory profile. In the BIOS, turn on XMP or EXPO. Memory at its slow default holds back frame rates in processor-bound games.You should see: The rated memory speed reported.
- Turn on upscaling if the game offers it. DLSS, FSR or XeSS render at a lower resolution and scale up, which usually gains a lot for little visible loss.You should see: A noticeably higher frame rate.
- Check the card is in the top slot. The slot nearest the processor is the full-speed one. Lower slots can run at reduced speed on some boards.You should see: Full link speed in the card maker’s tool.

The card is loud, or running hotter than I expected
Graphics cards are designed to run warm and will reduce their own speed rather than come to harm. Noise and heat are usually about airflow.
Usually one of these: not enough air moving through the case, dust in the cooler or filters, an aggressive default fan curve, or the card sitting against a panel with no intake.
Try these in order
Before you open the case: shut the PC down, unplug the power cable, hold the power button for about ten seconds to discharge it, then touch a bare metal part of the case to ground yourself. Never open the power supply itself, and never test or probe anything while it is plugged in.
- Check the case airflow path. One or two fans drawing air in at the front and one exhausting at the back is enough. A card with no cool air reaching it will run hot however good its cooler is.You should see: Lower temperatures once air can move through.
- Clean the filters and the cooler. Dust in the intake filters and between the cooler fins makes a large difference and is easy to miss.You should see: Lower temperature at the same fan speed.
- Set a gentler fan curve. The card maker’s tool lets you keep fans low until the temperature actually rises.You should see: Quieter at rest, still ramping under load.
- Check nothing is blocking the fans. A loose cable or a filter pressed against the card is a common cause of sudden noise.You should see: The noise stop once the obstruction is moved.
