Not sure how SLi works but ive just bought an 8600GT and ive still got my old 7600GS both SLi compatible, I guess i need a cable but what are the advantages of SLi? does it in theory double the speed?
Cheers

Hi Gooneruk

For SLI to work you need two Graphics Cards that match and say a DDR3 SLI Bridge, and a Motherboard that supports SLI "eg" two PCI-E slots. SLI (Scalable Link Interface) is a brand name for a multi-GPU solution developed by nVidia (thats two nVidia Graphics Cards running in sync on one Motherboard) this configuration when gaming works with (profiles) nVidia has created an extensive set of over 500 custom application profiles which enable SLI technology automatically and optimize scaling performance, you can also submit a request to have this profile for a game not in the list added to the next driver release.
