The disk in one of my Core2 quads died, so I've installed a new SSD and am starting to reload the system. It had 32 bit Windows on there before, but the chip is 64 bit I believe. I don't recall the reason for putting 32 bit on before, probably compatibility issues with some work stuff - no longer an issue. So I figured I'd install the 64 bit version, (Windows 8.1). Any reasons I should not do this?
