XPpro/SP2 64 bit

[Blind_Arrow]

I have AMD 64 BIT, but in very true opinion, do not use 64-bit O/S until Vista, as by then, probably 80% of the softwares should have become 64-bit, as now if you use 32bit applications on 64-bit o/s, they'll tend to be slow compared to running on 32bit O/S. i as well went to buy a 64-bit as when i bought mine 4400+, but at the last minute keeping all things in mind, I cancelled my program. also, there miht be some hardware driver issues also on 64-bit O/S. so better wait for Vista. like I am doing.
