Start your engines, all eight of them. Eight-core processing power was once only top-of-the-line. Now it comes standard. This time around, performance is more phenomenal than ever - up to two times faster than the previous standard-configuration Mac Pro. And with the multi-core technology enhancements of Mac OS X Leopard, the new Mac Pro is a force to be reckoned with. For what ever your working on, either Photoshop or Final Cut Pro enjoy up to 1.8 times faster processing power with this new Mac Pro. All-new high-performance graphics cards from ATI make Mac Pro graphics technology even more cutting edge. ATI Radeon HD 2600 XT with 256MB of GDDR3 memory, PCI Express 2.0, and two dual-link DVI ports - provides great performance for typical creative applications. The Mac Pro has four 3.5-inch internal hard drive bays that allows for an enormous amount of internal storage, up to 4TB. These bays are direct-attach and cable free, just attach the drive carrier to a Serial ATA hard drive and slide the drive into place. Another smart design allows you to install more memory in a snap. Mac Pro has two memory riser cards with four fully buffered DIMM slots each. Just slide out the riser cards and snap in the memory. With a total of eight DIMM slots available, you can install up to 32GB of 800MHz ECC DIMM memory. If you're looking for a powerful and a sweet looking desktop this is the one for you.
