Because Microsoft won't give me a new CD key after I lost my old one (Makes me mad, it was three years and three house moves since I bought it... I have photo proof ot the original CD, original receipt and the original manual!!! ) I've found that I can buy either XP Pro or XP pro 64 for under £100.
I have a new 3.8ghz 64bit P4 Dual processor thingy. the motherboard obviously supports 64bit.
Will my games and chat programs and so on still work on XP 64?
Is it faster? IE does it make better use of the P 4 D processor?
Thanks for your help.
