I guess the "wrong" way of testing is more helpful for me since I'll never have a 7800x3d and rtx 4090...
I don't need to know how a 7800x3d + rtx 4090 performs in games.
I need to know what GPU I should use for my meager 3800x and when a "better" gpu will not help giving any higher fps.
And I want that info placed right in front of me without having to extrapolate things from hardware I don't have or never will have.
