When considering the components of a gaming computer, most people think of the graphics card first. It can significantly affect frame rates, image quality, and the resolution you can comfortably play at, but it is not always a good idea to buy the highest-end GPU you can.
The first step in making a better choice is the games you play, the monitor you use and the rest of the hardware already in the PC.
Start With Your Gaming Resolution
Resolution can be a major factor in determining the amount of graphics power you really need.
A mid-range graphics card may provide ample graphics power for 1080p gaming without breaking the bank. The higher refresh rate and higher settings will require better graphics performance when switching to 1440p.
The workload increases greatly at 4K. Higher-end cards begin to start making more sense here as the GPU will be expected to render a lot more pixels per frame.
If you’re not a hardcore 4K gamer, spending money on a specific card for it is not going to help you much, as you’re set on using that same card with a standard 1080p monitor for the foreseeable future.
Match the GPU With Your Monitor
Monitor and graphics cards need to be thought of as a pair.
The 60Hz display won’t make use of the extremely high frame rates and a 144Hz or 240Hz gaming monitor will allow a faster GPU to do its job.
Adaptive-sync support can also help to make the game smoother when the frames drop.
Before choosing a gaming graphics card, look at the resolution and refresh rate of the display you already own or plan to buy. That gives you a much more useful performance target than simply comparing GPU model numbers.
VRAM Matters, but More Is Not Always Better
VRAM, or graphics memory, is the memory used to store textures and other information that the GPU requires during runtime.
High-resolution games with high-resolution textures can take up more VRAM, especially at 1440p and 4K. More memory means less need to sacrifice texture quality or to shuffle things around to keep the game from doing so.
But VRAM can’t tell you how fast a card is, however. Older GPUs with more memory may not be the most powerful.
Do Not Forget the CPU
Avoid forgetting to update the CPU.Don’t skip CPU updates.
A graphics card is unable to function independently.
At smaller resolutions and higher frame rates, the processor may be more significant due to its ability to create frames faster than the GPU.
This is especially obvious when playing competitively with players who might be chasing 144 FPS, 240 FPS, or even more!
Typically, at higher resolutions, the graphics card will bear more of the burden. This means the balance between CPU and GPU varies depending on the application(s) that are used.
The objective is not to remove all the possible bottlenecks. Simple enough to avoid using a very powerful part with hardware that can’t use it to any advantage.
Check Motherboard Compatibility
The motherboard is a key consideration in compatibility, as they should all be compatible with each other, but many modern graphics cards are built for the PCI Express slots.
A good gaming motherboard should provide the correct expansion slot, enough physical space around it and the features needed by the rest of the system.
The motherboard also dictates CPU compatibility, RAM support, the number of M.2 storage slots and some of the upgrade options available in the future.
For new construction, it would be better to focus on the entire platform instead of on the graphics card and the motherboard.
Check the Power Supply Before Upgrading
It’s also important to remember that a more powerful GPU might result in increased power consumption.
A new card will require a new card power connector, which must be compatible with the card and a PSU of the proper size. It’s better to use a high-quality PSU with some headroom than to run the system at the very limits of the PSU.
Physical dimensions of the power supply are not the only factor. Build quality, efficiency and the available connectors are important as well.
When upgrading a graphics card, make sure that you have budgeted for an old or lower-capacity power supply if a replacement is necessary.
Make Sure the Card Fits the Case
Contemporary graphics cards can be quite big.
Some more expensive models require multiple expansion slots and protrude well into the case. A card may be compatible with the motherboard, but not fit into the chassis.
Before purchasing, check the length, thickness and clearance of GPUs. The amount of usable space can be further limited by placing front-mounted radiators or other parts.
Airflow matters too. A high-quality graphics card in a small case can generate more heat and noise than the same card in a larger case, which offers a better cooling system.
NVIDIA or AMD?
There are cards available in various price and performance levels from both brands.
Compare cards from the same price range, rather than just on the logo. Consider actual game performance, electricity usage, VRAM consumption and features you expect to use in software.
Things like upscaling, frame generation and ray tracing are helpful, but it depends on what games you have in your library.
The best one would be the card that would offer you the necessary performance and features at the price you are willing to pay.
Final Thoughts
When you begin to look past “best” and “best” and “best” and start to consider whether you would like a graphics card with three, four, or five more gigabytes of video memory, the process of selecting a graphics card becomes much easier.
Begin with Monitor resolution and refresh rate. Play the games you want, test if the card can keep up and ensure that the motherboard, case and power supply work with it.
Generally, a balanced GPU will deliver more bang for your buck than the extra dollars you pay for more performance that goes to waste on everything else.
