XP 64 when it works is nice enough but only you will make the final verdict. I'd move onto Vista 64 if I wanted the best support.
I was wondering if a H.P phenom 2.6 gig quad 64 bit 6 gb with X.P would work? and if so what service pack would be needed? would I have problems running any software or applications? or is my hp.X.P X2 4gb the all the power /speed etc I could go? thanks
