Here are my options: 1. Vista Business 32-Bit 2. XP Pro 64-Bit Because of student deals, I am able to get either of these OSs for basically nothing. I tried to get Vista Business 64-bit but "that's not covered by this promotion." So my question is, which of these two OSs would be best for gaming on? I will be buying either the 24" iMac with the high-end Nvidia card or the stock octo Mac Pro with the 8800. I don't know if this matters, but the XP Pro would be a clean install and the VIsta Business would be an upgrade disc onto a current XP Home installation. Please share any suggestions on which of the two machines I should pick as well. I'll use it for mainly Dreamweaver, Flash, Illustrator, Office and code development on the Mac side and some coding work, but mainly gaming on the Boot Camp partition. I don't play Crysis and FPS stuff like that. I'm a MMORPG guy who would like to run Flight Simulator X as well. Thanks!
