Apple Nehalem Mac Pro

Intel's next-generation architecture comes to the Mac in the new Mac Pro ($2,500 and up). Featuring a single-die, 64-bit architecture, the Nehalem Xeons in the Mac Pro offer a performance boost of close to 2x the previous generation, and offer other speed advantages like integrated memory controllers, 1066MHz DDR3 RAM, and Turbo Boost, which automatically boosts the processor speed based on workload. Available in stock 2.66GHz Quad and 8-Core 2.26 models, they're the fastest Macs money can buy. If speed isn't your main concern, Apple's also offering new iMacs and Mac minis to quench your all-in-one or budget-sized thirst.
