I just ordered a new PC and I want to know if I should get windows 7 home premium, professional, or ultimate. I bought it for gaming and the basic specs are: AMD fx 8129 8-core, ATI radeon HD 8670, and 8 gigs of ram, and an internal WIFI card because I'll be running it off wifi. I'd like to get the cheap home premium version, but I've heard that to use wifi on a desktop and to use more than 4 gigs of ram you need professional, is that true? Thanks for the help
