Having installed Win11 on a PC with a 3570K it ran just fine. I don’t really see a difference in performance between 10 and 11 on desktops. I have an old ThinkPad with an i5 6300U and performance on that isn’t amazing, but I’ve never used 10 on it (bought it from the company I work for last year) so I don’t know if it doesn’t like 11 or that’s just how it is.
