Hey all, Given that it appears the GTX 285 "Mac Edition" is on the horizon (June 3rd?), can the mac pro physically (ie power, space, cooling) handle 2 GTX 285s in SLI in Windows? I understand that OS X does not support SLI so I wouldn't expect any performance gains there. Would it just ignore the card in slot 2 when I boot into OS X? Thanks for your info, I plan on ordering one (or maybe 2) when I get your answers.
