Feast your eyes.
All-new high-performance graphics cards from ATI and NVIDIA make Mac Pro graphics technology even more cutting edge. The standard graphics card an 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. And you get dual 30-inch Apple Cinema HD Display support out of the box.
For motion graphics, 3D modeling, rendering, or animation, youll need the greater graphics horsepower offered by the NVIDIA GeForce 8800 GT with 512MB of GDDR3 memory and latest-generation NVIDIA GPU technology.
The optional NVIDIA Quadro FX 5600 graphics card is the ultimate workstation-class graphics card available, with a massive 1.5GB of GDDR3 memory and a 3D stereo port for stereo-in-a-window applications.
All of these cards feature the latest-generation unified shader model support. Compared to dedicated pixel and vertex shaders, shaders are no longer special-purpose and can now be utilized based on the needs of the graphics application.
PCI Express 2.0.
Its the latest interface technology available for connecting high-performance graphics cards, and its new to the Mac Pro. A 16-lane dedicated graphics slot now features PCI Express 2.0 with up to twice the transfer rate of PCI Express.
The even bigger picture.
To create an incredible display wall or large-scale visualization, install up to four graphics cards, each with two dual-link DVI ports. You can run up to eight 30-inch Apple Cinema HD Displays at the same time with just one Mac Pro.
