Prices are approximate US street prices in October 2026 and change often; see the GPU price tracker.
Which 4K graphics card should you buy?
You should choose a 4K graphics card by budget and goal:
- RTX 5090: for native 4K at maximum settings with path tracing, if price is not a concern.
- RTX 5080: for 4K at 100+ FPS with DLSS and frame generation.
- RTX 5070 Ti: for 4K at 60–100 FPS with DLSS, the most balanced choice.
- RX 9070 XT: for 4K with FSR 4 at the lowest price per frame.
How much VRAM do you need for 4K gaming?
You need 16 GB of VRAM for 4K gaming in 2026. Cards with 12 GB or less run short of memory at 4K with high-resolution textures, which causes stutter; see what shared GPU memory is.
Can a mid-range GPU run 4K?
Yes, mid-range GPUs such as the RTX 5070 and RX 9070 can run 4K with upscaling (DLSS or FSR in Performance mode) and medium-to-high settings. For native 4K at high settings, a card from the table above is recommended.
What power supply do you need for a 4K GPU?
You need a power supply of 750W for the RTX 5070 Ti and RX 9070 XT, 850W for the RTX 5080 and 1000W for the RTX 5090, plus the correct connectors; see do GPUs come with power cables.
What else do you need for 4K gaming?
You need 3 more things for 4K gaming: a 4K monitor (ideally 120–144 Hz with G-Sync or FreeSync), a CPU that does not bottleneck the GPU, and a DisplayPort 1.4/2.1 or HDMI 2.1 cable. Read CPU vs GPU to balance the build.
