I'm a big WoW player and I have a MBP when I'm on the road. My main PC rig is just about ready to go to the curb and I'm thinking of replacing it with a new Mac Pro 3GHz and an Apple 23". Here are my questions: Sound - is there a way to get more than stereo sound of of a Mac Pro? Can I add a Creative Labs sound board or is there a way to get 5.1 out of the optical port? Performance - anyone have any experience running WoW on the new Mac Pro's. I was wondering about frame rates and performance at the upper resolutions. Video Card Recommendations: If I have a 1900 and 7300 - is it possible to run WoW on the 1900 and other (open) applications on the other display (Safari, Mail, Vent, iChat etc.). Has anyone figured out if we can do SLI if we are running Windows XP? Thanks. Tommy.
