Well the new MacPro (not the final release version) is showing up in MacBench scores according to MacRumors, and the results are pretty good. Currently getting a 23901.
My MacPro model stock rates an 11970, and mine currently rates at 13510, so it is about the speed of my stock machine faster. Pretty impressive. Still there are Hackintosh’s easily getting 28000 or higher (if overclocked), so it is not as impressive as it could be!
