go with vista x64 oem from newegg. there isnt a really big difference between xp and vista. since you have a gaming rig, the small performance hit by vista wont lower your frames at all. As the case of windows 7 beta, dont punkbuster will annoy you to death as both the cods dont work. But if you really want windows 7 get the release candidate coming may 5. The RC is extremely stable, and fixes many of the punkbuster issues but not all of it.
all in all get vista x64 home premium, and upgrade to windows 7 when it releases.
