NVIDIA\'s fourth-generation GPU architecture built for Windows Vista gives users the best possible experience with the Windows Aero 3D graphical user interface. World\'s first DirectX 10 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realism and film-quality effects. Shader Model 4.0 adds support for indexed temporaries which can be quite useful for certain tasks.Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers. This is typically not possible for indexed temporaries thus the register pressure of the shader may increase dramatically. This could be detrimental to performance as it reduces the hardware’s ability to hide latencies. PCI Express 2.0 –Now you are ready for the most demanding graphics applications thanks to PCI Express 2.0 support which allows up to twice the throughput of current PCI Express cards. Doubles the bus standard\'s bandwidth from 2.5 Gbit/s (PCIe 1.1) to 5 Gbit/sec. Massively multi-threaded architecture supports thousands of independent simultaneous threads providing extreme processing efficiency in advanced next generation shader programs. Available on HD DVDs and Blu-ray discs high-definition movies are bringing an exciting new video experience to PC users. NVIDIA PureVideo HD technology lets you enjoy cinematic-quality HD DVD and Blu-ray movies with low CPU utilization and power consumption allowing higher quality movie playback and picture clarity.PureVideo HD technology provides a combination of powerful hardware acceleration content security and integration with movie players plus all the features found in PureVideo.
