I'm planning on removing my OEM board and CPU & Memory, and replacing those three with something faster. I'm planning on moving from a P4 to an AMD Athlon 64. Since I never had a 64bit CPU, I never read up much about the 64bit version of Windows. Can anyone explain to me what the differeneces are, and if I need it? Also, on a related question, can I still legally use the OEM version of Windows XP that came with this computer if it's no longer installed on any other system? Or is it permanently tied to that mobo/cpu? I don't need to use a restore CD, I have the a standard OEM Windows XP installation for that computer.
Thanks!
Thanks!
