I can’t decide between a 7960x (delidded, but with warranty) and a 1950x. Price difference isn’t an issue, but if there is no significant difference between even a 4.5ghz oc 7960x and a 4.1ghz oc 1950x in vegas pro 15, I’m getting the cheaper cpu.
What is significant? Well, it has to be noticeable IRL, so probably (10-)15%+ I would say. I run windows 10 btw and am also getting a 1080 ti, which could be utilized for vegas.
