Heh, I thought this was another thread about burning up a processor or something.
I figure the XP isn't dead, but it's being phased out. The 64 is the progression of AMD's product line; there's no reason for them to continue to develop old and inferior technology for much longer. Of course, so many people have Athlon XPs, so there's no shortage of stuff for them, but... Yeah, no more Athlon XP development. 3200 is as high as they go.
