I just installed the 301.34 with modded .inf by Spets (at Guru3D.com). It seems to give a nice boost to those of us running SLI systems. The driver was released only for the 6-series...the 690 being SLI based, dual GPU. My framerate, which has always been smooth, got a nice shot in the arm. You'll need to extract the unmodded driver download, then drop the modded .inf file (downloaded separately) inside the display.driver folder prior to starting setup. Accept the install signature warning to continue install. It also has a newer audio component. The only side effect is that on computer shutdown, you'll physically have to reach over and turn off the power button yourself. I can do that, given the added performance.
