I've decided to finally upgrade from my old EVGA 123-LF-E653-KR (P55 LE) to either a ASUS P8Z77-V PRO or an ASUS SABERTOOTH but regardless of that I was wondering what I'd need to go about doing to upgrade? Do I just swap the board, plug everything back in and play or will I have to reinstall windows? Is there a way to upgrade without having to reinstall everything?
