I didn't even think of it when I ordered my new system. I currently have the same copy of windows xp home I've had all along. Do I need to get 64 bit XP professional for my Athlon 64 X2 dual core processor to work? I'd hate to have to have to buy a retail copy.. argh Thanks <no links - in sig only>

The expert here reckons you can but you'll lose the 64 bit capability of the machine

From what I've read about this, very few programs make use of the 64bit version of XP.

Hello Luis101 A 32-bit program might run slower on Windows XP Professional x64 Edition than it would on Microsoft Windows XP Professional. Alternatively, some 32-bit programs that require lots of memory may exhibit increased performance on the x64-based versions of Windows XP Professional x64 Edition. Maybe best to wait for Vista.
