NVIDIA GeForce RTX 4090 / Ryzen 9 5950X
In terms of cost, pricing clearly is a genuine issue here and the price of RTX 4090 is simply ridiculous. For those on 1080p or even 1440p monitors, the RTX 4090 is very expensive and there are better value choices in the short term. It is worth noting that the RTX 4090 is a very power hungry card and requires a decent power supply unit. In terms of memory, the RTX 4090 's 24576 MB RAM is more than enough for modern games and should not cause any bottlenecks. 4K gaming is joyous on this RTX 4090 , and with a little tweaking to your AA settings, it'd be hard to imagine a title not capable of 60 fps on average.AMD Radeon RX 6900 XT / Core i9-10900K
