We were expecting it, and now Apple have gone and done it. Just up on the Apple Store is the new 8 Core Xeon Mac Pro. Just to get you straight, that's two quad core chips in there, both clocking in at 3GHz. Speedy. Base configuration is $4000. If you max out all the options you're looking at $12,100. And you don't even get a built in iSight.
