Nvidia Driver Issue - 660Ti SLI

I have 2 - 2GB EVGA 660Ti cards in SLI.  There appears to be driver issues.  Driver v310.14 works, but stutters and lags terribly.  Any driver above this won't even work in SLI.  I get a driver error and have to restart the PC.  Driver 306.97 is the only driver I can get to work with the SLI setup and actually runs pretty smooth.  

Anyone else experience this issue or similar scenario?  Know of any fixes or potnential news updates that might correct the driver issue?  Don't want to be stuck using v306.97...

Forgot to mention, I experience the stutter and lag issues while playing BF3...
