Little more than two years have passed since NVDIA first introduced their SLI technology. Short for Scalable Link Interface, SLI is the first solution to be able to connect two PCI-Express video cards based on the same GPU in a way that they will operate parallel to each other. This type of approach allows, at least on paper, to have an increase in performance of up to double what you would normally have with a single video card. In the first months of SLI’s release, it potential was limited by driver problems and other software errors.
However, forwarding two years into the future and with the release of several new driver versions from NVIDIA, SLI technology has really matured as a whole. Stability has been greatly improved and support has been added to an increasing list of games. SLI support has also been made more accessible to the general public with the release of average and entry level video cards that support the technology. Currently, SLI will even be made available on NVIDIA’s most budget level class of GeForce 7 video cards, the 7100 GS, thus making it a solution that is affordable and available to a vast amount of computer users.
At this moment, SLI and Crossfire technologies can be considered the first full phase of maturity for a broader category: multiple GPUs. The next phase is for more than two video cards being linked up to each other in an effort to, yet again, increase performance. As NVIDIA was first to reach the market with a dual video card solution, they have yet again been able to beat ATI in announcing a solution that utilizes more than two GPUs. The technology is, none other than, Quad SLI (the name isn’t very original). Quad SLI has four GPUs operating parallel to each other, theoretically doubling the performance in respect to an SLI setup.

This here is a great link to view how much performance can you gain by building a SLI rig. Great link so you must check it out.
