I'm still running the upgrade install... feeling no need to do a clean install either. And you're probably right about the whole HW/SW issue. Kinda like back in Vista days. People complained about it left and right, saying it was garbage and hardly worked.... but mine worked just fine. So long as i had certain BIOS settings configured in a certain way, anyway. Think even if i tried to overclock a smidge, Vista would throw a fit in minutes.
