AMD Radeon RX 6950 XT / Ryzen 9 5950X
In terms of cost, pricing clearly is a genuine issue here and the price of RX 6950 XT is simply ridiculous. For those on 1080p or even 1440p monitors, the RX 6950 XT is very expensive and there are better value choices in the short term. It is worth noting that the RX 6950 XT is a very power hungry card and requires a decent power supply unit. In terms of memory, the RX 6950 XT 's 16384 MB RAM is more than enough for modern games and should not cause any bottlenecks. 4K gaming is joyous on this RX 6950 XT , and with a little tweaking to your AA settings, it'd be hard to imagine a title not capable of 60 fps on average.NVIDIA GeForce RTX 4090 / Ryzen 9 5950X
