Spec nerds felt a momentary spike in their britches today when Geekbench turned up a Mac Pro with a 3.19GHz Intel Xeon X5580 processor. "No," you're supposed to mutter knowingly, "the current top-of-the-line Pro only has a 2.93GHz X5570." Was this some Cupertino super Mac busting forth with a score of 18765? In the end, the answer was "No...?" The chip was explained by a processor update, but there was still some unsolved BIOS mystery. Intense, right? [PC World]
