Hey guys, I'm wanting to upgrade my wifes computer from 32 bit Vista to windows 7. I cant seem to find information to tell me if it will support a 64 bit windows 7, but i suspect that it may. Here is a link to this pc http://www.buy.com/prod/acer-aspire-ase380-ud440a-desktop-pc-2-2ghz-amd-athlon-64-x2-4400-2gb/206181434.html ...I have a 64 bit windows 7 on hand that would be convenient. Which can i use?
