I wonder how much of a hit, if any that’s causing?Also, reviewers only test clean installs with modded windows to remove all bloat. Meanwhile when I buy a CPU it goes into a system with a 2 year old install filled with apps and bloat. It's one of the reasons I won't buy an 8 core CPU
I’ve always been under the impression that a clean install is a must and can cause all kinds of issues. Obviously yours must be fine.
