Short answer: Buy the GPU for your target resolution and refresh rate, and make sure it has enough VRAM to last. Check it fits your case and your power supply can feed it before you commit. Chase real-world benchmarks at your resolution rather than headline specs, and weigh upscaling and ray-tracing support if those features matter to you.
The graphics card is usually the biggest lever on gaming and creative performance — and the biggest cost. Here's what each spec means, how much it moves our 0–100 score, and what's normal across the cards we track. With well over a hundred GPUs in our catalogue, the medians are a solid market baseline.

A GPU's specs don't translate cleanly across architectures, so the reliable way to choose is real benchmark performance at your target resolution and refresh rate. Decide the goal first — 1080p high-refresh, 1440p, or 4K — then find the card that hits the framerate you want there. Buying far more GPU than your monitor can show (or far less than your resolution demands) is the most common, and most expensive, mistake.
Video memory is the quiet longevity spec. Our tracked cards run a median 12GB, and 89% carry at least 8GB while 58% have 12GB or more. Running out of VRAM causes stutter and forces lower textures no matter how fast the chip is, and higher resolutions and texture settings eat more of it. For 1440p and 4K, and to stay comfortable for years, lean toward more VRAM — it ages better than raw speed.
Memory bandwidth, bus width and clock speeds feed the GPU, and a bottleneck anywhere caps real performance — but these numbers only compare within the same architecture. Compute figures like FP32 (our median is 12.1 TFLOPS) hint at raw throughput yet rarely track gaming performance one-to-one. Treat these as context for a benchmark result, not a substitute for it.
A fast card you can't fit or feed is useless. Our tracked GPUs draw a median 280W, and the high end pulls much more — so confirm your power supply has the wattage and the right connectors, and that the card physically fits your case (length and slot height). More power means more heat and noise, so cooler design and case airflow matter. These practical checks prevent the most frustrating build-day surprises.
Beyond raw speed, feature support can change which card is the better buy. Ray tracing adds realistic lighting at a heavy performance cost, and cards differ a lot in how well they handle it. Upscaling tech (DLSS, FSR, XeSS) reconstructs a higher-resolution image from a lower one to boost framerates, and the quality and game support vary by brand — it can effectively give a card a second life. If these matter to you, weigh them alongside benchmarks rather than after.
