Hi all. I've recently built my own computer for gaming (about a $1500 rig) and when I went to install my Win7 Cd... it was the upgrade disc. Long story short I eventually got Windows 7 Pro (32bit) working on my computer for now. *However* I built my rig for a 64 bit operating system. I'm planning on upgrading to Windows 8 Pro, but I'm curious to if a Win 7 32 bit installation will be compatible with a Win 8 64 bit installation? I'll post specs if needed but I'm 100% sure I have the muscle to run Win 8 and everything else just fine.
