Up to 5x faster standard graphics.
High-performance graphics cards from AMD make Mac Pro graphics technology up to 5 times faster than ever before.1 Perfect for motion graphics, 3D modeling, rendering, or animation, the ATI Radeon HD 5770 with 1GB of GDDR5 memory comes standard. It not only provides faster performance compared to previous Mac Pro standard graphics cards — it’s also faster than the top-of-the-line graphics cards in the previous generation.

Give your graphics a turbo boost.
For even more graphics horsepower, upgrade to the ATI Radeon HD 5870 with 1GB of GDDR5 memory. An ideal choice for the most demanding applications, this card features a wider memory bus and higher-performance GPU, resulting in up to 70 percent faster performance compared with the ATI Radeon HD 5770.2

känns lite skumt att de sätter in ett 5770, ett mellanklasskort från förförra generationen i en dator som ska vara en highend workstation dator som kostar uppemot 25000 (för den billigaste med 4core cpu.) men man kan ju alltid köpa ett 7970 eller liknande eftteråt
