Nvidia has offered enthusiasts a pre-release version of Quad SLI drivers that allow two GeForce 7950 GX2 cards to work together in perfect harmony - or as near to it as beta-test software allows, at any rate.

To run drivers, do-it-yourselfers will need two 7950 GX2s, natch, but also motherboard fitted with an Nvidia nForce chipset capable of supporting SLI and the 7950 GX2. They'll also need a power supply capable of delivering more than 700W, Nvidia said.

The ForceWare 90 drivers are release 91.37 - the current standard release is 91.33, which added support from the GeForce 7950 GX2.

You can download the drivers from Nvidia's SLI website. ®
