If you wish to play at 4k max settings it's already on its knees if the game doesn't have DLSS.
Who hunts Native4K unless you got a 4090.
Ive got a 3440x1440p144Hz monitor.
I do use DLDSR when I can or straight DSR but UW1440 x 4 is very heavy on the GPU.
Max settings does very little to my lowly 6 cores and 16GB of RAM.
My GPU is bottleneck'ing me more often than not thus the upgrade to a 4080'20G
But the core count and RAM count arent really affecting my game.
The highest ive seen so far is 12GB of RAM usage.
But Im not going to get over 6 P-cores any time soon cuz until the PS6 if even then........I doubt any major AAA game will benefit greatly from having 8 or 10 or 12 or 16 cores vs simply have 6P.
P.S
<---- One of the people who always champions 6 cores cuz bang for buck and some good binning is king.
