This may sound retarded, but...

Do you need a certain kind of windows xp to run the am2 processor?

i mean do you need windows xp pro x64?

You can use WindowsXP if you want to run your AM2 CPU simply as a fast 32bit CPU. You'll need a 64bit Windows if you want to run it in 64bit mode, WindowsXP 64 or later this year Vista. Right now there is almost no reason to run in 64bit mode, nor are there many apps or drivers for 64bit out.

thats exactly what i needed to know, thank you.
