TUAW reports that the Mac Pro did see a bit of a speed bump today
The online Apple Store is showing new configurations of the Mac Pro. Previously, a 12-core 2.93 GHz model was the speediest Mac Pro available; now a 12-core 3.06 GHz CPU model tops the charts, featuring Xeon X5675 processors. Apple shows this as being "up to 1.3X greater than the previous-generation Mac Pro."Mac Pro gets an unannounced speed bump
