I am moving from my i9-9900k to an R7 5800X. I have heard that transferring drives with windows on it from one platform to the other causes issues with performance and general stability. Many advise running a fresh install of windows onto the system. I was wondering if a "fresh start" will have the same effect as a fresh install from a USB since I am not looking to buy a new drive or completely wipe an existing one. Windows version and build should be the latest; don't have exact numbers since my past PC died.
