Well, the discovery that Civ IV expansions don't have a snowball's chance of moving to mac native finally pushed me over the edge. I want to set up boot camp on my early 2008 mac pro. I think I will install XP on a new HD (third bay.) What do I need to do to make sure I can play games well and basically out of the box? Will the seperate HD work? Is partitioning an existing drive a better idea? What size/speed/kind of HD should I buy? Which version of XP should I buy? Should I just get Vista instead? I know there are answers sprinkled throughout this forum, but I thought I'd be a little lazy and see if I could get comprehensive answers here. Thanks ahead of time.
