Is the 7600 build the offical one or what ???

Yup and it runs nice 

yeah was wondering cuz iv read that it might not be but i want to ask what you guys think, cuz maybe iv been reading the wrong thing. lol but yeah thats really cool, and when does it come out?

Build 7600 is what the OEMs will use and what you get through Technet and MSDN. It's the RTM build. The retail copy will probably be the same build and will come out Oct 22.
