Q9450 OC / Temps / Settings

[tdenton1138]

Ok I have a really dumb (read: ot) question. My rig (mobo and cpu) just fried. I went back about 2 months in this thread and have read pretty much every post since and I've finally decided to jump from my dead e6600 etc to a 9450, p5q deluxe and 4g of ocz plat pc8000. um... XP only supports 2 cpus, right? So I am forced to Vista? Or am I hallucinating here late at night.

edit: And does it matter if I get the p5q deluxe or p5q-e as far as overclocking goes?

and again: Is there a reason to get or not get the 64 bit version of vista... and does 'ultimate' matter? I seem to recall hearing about some driver issues along those lines.
