I just built my gaming rig and I want to have windows 8 on there ASAP because I want to start playing skyrim on max settings and stuff. I ordered windows 8 system builder on Sunday and it's coming tomorrow but I've been waiting all summer to get my motherboard fixed so it would work and I want to see if Windows 8.1 preview will work. Will it? If it does, would I be able to uninstall it, then put windows 8 pro on it?
