Just like its little brothers and sisters from the GeForce 8 family, the 8800 Ultra has a full support for Shader Model 4.0. Compatibility for DirectX 9 and 10 and Vista, as well as support for High Definition content with the NVIDIA PureVideo HD technology. In other words; everything you'd expect from a Point of View Graphics Card, but stronger, faster and cooler.
It's available today but they didn't say how much it will cost. According to GeForce 8800 Ultra reviews the card is priced at $829 in the U.S.
