SLI from NVIDIA

"What is NVIDIA SLI Technology?

NVIDIA SLI is technology that combines two or three SLI™-Ready GeForce® graphics cards with an SLI-Ready NVIDIA nForce® motherboard to significantly boost the graphics horsepower of a single-card desktop system. You can also take your awesome gaming prowess on the road with a pre-configured NVIDIA SLI notebook.

NVIDIA® SLI™ technology is a revolutionary platform innovation that allows you to intelligently scale graphics performance by combining multiple NVIDIA graphics solutions in a single system with an NVIDIA nForce® SLI media and communications processor (MCP).

How Does SLI Technology Work?

Using proprietary software algorithms and dedicated scalability logic in each NVIDIA graphics processing unit (GPU) and MCP, NVIDIA SLI technology delivers up to twice the performance of a single graphics solution.

Quad NVIDIA® SLI® Technology

Take the acclaimed NVIDIA® SLI™ technology to the next level with a pair of über-powered, dual GPU GeForce® 9800 GX2-based graphics cards running in Quad NVIDIA SLI® mode. Quad SLI enables up to four GPUs, 512 cores and 2GB of high speed graphics memory working simultaneously to deliver a 3.4x performance increase over a single GeForce 8800 GT. And combined with the speed, overclockability, and next generation features of an NVIDIA nForce® 790i Ultra SLI motherboard, you can build the fastest NVIDIA gaming platform to date and power through the latest Microsoft® DirectX® 10 games in Extreme HD resolutions.
