Pentium (r) D CPU 2.80Ghz 2.80 GHz, 1.98 GB of RAM This is all the specs she gave me. She's currently running windows XP and she's wanting to add 2 more gigs of ram. I know that XP won't use anything past 3 gigs, though. So, I'm just wondering. She's wanting Windows 7 64-bit but I don't know much about 32 bit and 64 bit. So, which should she get? Thanks for the help.
