At A Glance

The new Mac Pros, with their cutting-edge Nehalem processor technology, are able to execute more tasks at a faster clip, despite lower processor speeds. And their new internal design makes adding hard drives, memory cards, and PCI Express 2.0 cards easier than ever. The 2.66GHz quad-core Mac Pro , which out-performed the other Mac Pro in our tests, would be a fine purchase for anyone replacing an older Mac or buying a new one for the first time.

Manufacturer’s Description

The new Mac Pro introduces Turbo Boost: a dynamic performance technology that automatically boosts the processor clock speed based on workload. If you're using an application that doesn't need every core, Turbo Boost shuts off the idle cores while simultaneously increasing the speed of the active ones.
