Be forewarned that recent nvidia geforce drivers have a tendency to damage GPU cards (http://pcpartpicker.com/forums/topic...may-damage-gpu).

So I suggest you update to the latest driver version (which is 331.69). I have 2 GTX560Ti in SLI (MSI Twin Frozr II & ASUS DirectCuII), and I don't have any problems with both cards. Was using 314.07 version and decided to update to 314.21 and it was worse, so rolled back to 314.07 and never update ever since. But when I was told by my friends that the latest update was released and there aren't any problems. I finally decided to update (to version 331.69) and it even got improved performance in SLI.

Oh yeah, make sure to configure the geforce experience app to not update the driver automatically. You'll never know if there will be a next version update where it can do more harm than good on your GPU card.
