Service Pack 3 is compatible with all 32-bit versions of Windows XP, so no matter if you're on Professional, Home, or Media Center Edition, you'll be able to get all of the updates and improvements.
For gaming XP64 is not a patch on XP32/Vista in my experience.
And my experience is the opposite. Oopsie, there goes a spanner in the works.For gaming XP64 is not a patch on XP32/Vista in my experience.
XP 64 gets less support than Vista 64, has always been that way and it wont change now, SP3 will be last SP for it but the support for drivers etc from 3rd partys aint the best IMO.
I never used my free Vista Testers copy of Vista 64Ult for 1 year as of support issues.
