Thanks to the next-generation Quad-Core Intel Xeon “Nehalem” processors  and new system architecture, the Mac Pro now delivers performance thatʼs  nearly twice as fast as before.(1) Each processor features an  integrated memory controller and 8MB of fully shared L3 cache. With  blazing-fast 1066MHz DDR3 ECC SDRAM, high-performance graphics, a  redesigned interior for easier expansion, itʼs the most advanced Mac Pro  ever.

Featuring  a single quad-core Intel Xeon processor and all-new ATI graphics, the  Apple Mac Pro desktop PC delivers amazing performance and expandability  for the most demanding consumers and professionals. This Mac Pro (model  MC560LL/A) is powered by a single hyper-threaded 2.8 GHz Quad-Core Intel  Xeon "Nehalem" series processor with a Turbo Boost feature that  automatically boosts the processor clock speed based on workload. It  also features the ATI Radeon HD 5770 graphics processor with 1 GB of  GDDR5 memory.

This  Mac Pro is outfitted with 1 TB of hard drive storage and 3 GB of 1066  MHz DDR3 RAM. The interior provides easy access to all components within  the Mac Pro for hassle-free expansion and massive upgrade ability--up  to 32 GB of RAM and four hard drive bays for up to 8 TB of storage under  the hood. And while it comes standard with a 18x SuperDrive (compatible  with burning DVD±R/RW and CD-R/RW discs), you can also add a second  writing SuperDrive.
The Mac Pro also now features two Mini  DisplayPorts and one dual-link DVI port. The additional Mini DisplayPort  output allows you to connect two displays without an additional  graphics card or adapter, and the dual-link DVI port supports legacy  DVI-based displays up to a resolution of 2560 x 1600 pixels.  Continuing  Apple's commitment to the environment, the new Mac Pro meets Energy  Star 5.0 requirements, and its enclosure is made of highly recyclable  aluminum while the interior is designed to be more material-efficient. 
It  comes pre-loaded with Apple's Mac OS X 10.6 Snow Leopard operating  system--an operating system custom-designed for the advanced technology  inside--and it also comes with the iLife suite of applications,  including iPhoto, iMovie, GarageBand, and iTunes.

Expansion Made Easy
The  easy-access interior of the Mac Pro feels like the well-organized  workstation it is. No rat's nest of components here. You don't need to  turn the system on its side or struggle to reach into awkward spaces to  make changes. Just remove the side panel for instant access to  everything. Slide out the processor tray to add memory. Slide out drive  bays to add storage. Slide a simple bar to change up to four expansion  cards at once. And with plenty of I/O ports both front and back, you'll  have room for all your external devices.
Tool-less PCI
When  it's time to upgrade, a quick slide of the retention bar frees up the  four expansion card slots for easy access. Thanks to a thumbscrew PCI  bracket, you can swap out cards without any tools. All four slots are  PCI Express 2.0 for incredible performance. And since the graphics slot  in the Mac Pro is double-wide, your graphics card won't cover an  adjacent slot.
Slide-in Storage
The  Mac Pro comes with four 3.5-inch drive bays for an enormous amount of  internal storage--up to 8 TB. For faster access to your data, you can  also configure your Mac Pro with up to four solid-state drives. The bays  are direct-attach and cable free, so it's easy to add or remove drives.  Just attach the drive carrier to a drive and slide the drive into  place. There are no connectors or cables to contend with. Lock the  drives with the side door latch, and you're done.
Snap-in Memory
Install  more memory in your Mac Pro in a snap. Literally. The easy-access  interior lets you slide out the processor tray in one smooth motion,  then simply snap new memory into place. You don't have to dig around  inside the computer or wrestle with wires or cables. This  single-processor Mac Pro offers four slots that support up to 16 GB of  DDR3 ECC SDRAM.
The Greenest Mac Pro Yet
Even  though the new Mac Pro is the fastest Mac ever, it is also highly  energy efficient. Energy-efficient hardware components work hand in hand  with Mac OS X to create a system that can dynamically adjust power  consumption to reduce the overall energy used. For instance, the CPU  architecture allows individual cores to go into a low-power state to  reduce energy consumption when they are not needed. The graphics card  does the same, reducing power draw when not running graphics-intensive  applications. The result is a smart and energy-efficient system that is  not only as fast as possible when you need it, but also throttles down  power use when it's not needed.
The Mac Pro meets the stringent  low power requirements set by the EPA, giving it ENERGY STAR  qualification. ENERGY STAR 5.0 sets significantly higher efficiency  limits for power supplies and aggressive limits for the computer's  typical annual power consumption.
Pre-Loaded with Mac OS X Snow Leopard and iLife
Every  Mac comes with Mac OS X Snow Leopard, the world's most advanced  operating system, and iLife, Apple's innovative suite of applications  for managing photos, making movies and creating and learning to play  music. Snow Leopard builds on a decade of OS X innovation and success  with hundreds of refinements, new core technologies and out of the box  support for Microsoft Exchange. iLife features iPhoto, to easily  organize and manage photos; iMovie with powerful easy-to-use new  features such as Precision Editor, video stabilization and advanced drag  and drop; and GarageBand which introduces a whole new way to help you  learn to play piano and guitar.
