4K picks.
4K is honest: it punishes weak cards and thin memory buffers immediately. The realistic entry point is $600, the comfortable zone starts around $1,000, and the ceiling is whatever a 5090 costs this week.
The ranking
6 cardsGeForce RTX 5090
The fastest consumer card on earth, and the only one with 32GB. You pay for every gram of it.
GeForce RTX 5080
Excellent 4K card with one asterisk: 16GB is half what the card above it gets.
Radeon RX 9070 XT
The best raster value in the current generation. The card NVIDIA has to price against.
Radeon RX 7900 XTX
The cheapest way to 24GB of VRAM in a card you can still buy new.
GeForce RTX 4090 (used)
Out of production, still in demand: 24GB of CUDA keeps its used price stubborn.
GeForce RTX 5070 Ti
The NVIDIA card most people arguing about the 9070 XT actually end up buying.
