Gaming in 4K is the Holy Grail for many gamers: ultra-fine textures, details, maximum immersion. But it requires serious hardware. The ideal 4K video card must offer raw power, good ray tracing management, good upscaling, and a reasonable performance / price ratio.

The RTX 5090 , it's the ultimate card. 32GB of GDDR7 VRAM, monstrous performance, and a price... just as monstrous.
If you want the top of the top and you don't care about the budget, go for it. Otherwise, honestly, it's "too much".
If you come across a good RTX 4090 used, go for it. It remains formidable in 4K, even against the 5080.
You lose a few percentage points of performance, but you often save several hundred euros.
If you want to play in 4K If you want a smooth experience without blowing your budget, go for the RTX 5080. The RTX 5090 is dreamy, but unless you have a 4K 240 Hz screen and a monstrous power supply, it's a waste. And for the savvy ones, a well-negotiated RTX 4090 remains an excellent 4K video card.
