You cant buy a cpu based on 1 game unless that's the only game you are going to play. That's why you look at averages across multiple games. On average the 3d ain't worth it unless you plan to buy a 5090 and game at 1080p.
cough, look at the games at 4k, cyberpunk with 3900x get 75.5FPS, why bother get anything newer if you arn't chasing for "future proof" in whatever usecase you are building the PC for?
As per your arguement, if one arn't planning to plug a 4090 into a zen 1 or 7700k, the GPU will bottleneck the game to settings where zen 1 or 7700k won't matter.
