Ive just ordered a athlon x2 4200+ from OCUK (£88.41 with next day delivery ), will have it tomorrow. Ive got a dual boot system with XP and vista. Am i likely to run into problems with the OSes when i change the processor over? Is there any easy workarounds, or am i likely to need to reinstall? I think i might getaway with a repair of XP, but im not to sure about how vista works with stuff like this. Cheers
