NVIDIA SLI (Scalable Link Interface)
NVIDIA SLI (Scalable Link Interface) technology is a revolutionary approach to scalability and increased performance. NVIDIA SLI takes advantage of the increased bandwidth of the PCI Express bus architecture, and features hardware and software innovations within NVIDIA GPUs (graphics processing units) and NVIDIA nForce4 MCPs (media and communications processors). Together the NVIDIA SLI patent-pending technologies work seamlessly to deliver heart-pounding PC performance. And depending on the application, NVIDIA SLI can deliver as much as 2x the performance of a single GPU configuration for unparalleled gaming experiences.

NVIDIA PureVideo HD Technology
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.

High Dynamic Range (HDR)
High dynamic-range(HDR) lighting effects bring environments to life for a truly immersive experience. It takes advantage of the subtle light, texture, and color intricacies to create incredibly realistic environments.

Windows Vista Ready
Windows Vista is the first operating system to require a GPU (Graphics Processing Unit) to realize the best experience possible.

PCI Express 2.0 Support
PCI Express Base 2.0 specification doubles the interconnect bit rate from 2.5 GT/s to 5 GT/s in a seamless and compatible manner. The performance boost to 5 GT/s is by far the most important feature of the PCI Express 2.0 specifications. It effectively increases the aggregate bandwidth of a 16-lane link to approximately 16 GB/s. The higher bandwidth will allow product designers to implement narrower interconnect links to achieve high performance. (backwards compatible with PCI Express)
