Until then I am happy with 80fps or more. The older drivers for the cards work fine and I will get really high FPS(over 140) however I like to have the newest drivers installed on my cpu so I will wait for them to release new drivers that fix the problem. You get massive screen tearing when you enable SLI. However, Currently there is a problem with SLI and the current drivers. I currently get over 80fps all the time with SLI Disabled.
