Has anyone bought one of these cards and tested it on a mac pro yet? I'm about to run to Fry's to grab one of these cards...Since I wanna use it in Windows. For Mac OS X, I'm not so sure about? It'll probably detect the card, but have no drivers I'm assuming? Too bad the Mac Pro doesn't have any PCI slots...I'd be using my X-Fi from my PC rig if it had it! Anyone wanna shed some light on this subject before I plump $69 on it? Thanks!
