SLI Support?

[Wolo]

Rick Rusky, i tried your sli config but i have bad results. My fps are ranging 20/60 (vsync on) and have lots of stutters. Im new to sli, just bought a second hand gtx 580 3gb phantom last week and im trying to configure to clod.
Im using nvidia drivers 301.42 and the last beta patch, do you have your sli config working on the last nvidia driver? or you are still using 285.27?
Im not sure if changing this can improve my sli performance.
