Performance is atrocious! Stuttering like a mofo, even on LOW settings. On the Auto settings, I have nearly maxed GPU Memory usage (like 1965 MB) and on the lowest its about 1800....
Make sure full screen is enabled explicitly in the menu. You'll need this to have SLI working and by default it's windowed mode

Also make sure you've got the latest beta drivers installed as they contain the SLI profile.
1965MB is fine - I used to run similar level at triple screen res with SLI 680s with performance OK all things considered
