Default GTX 660 not performing to full potential?

I was expecting my new GTX 660 to outperform the GTX 570, which it didn't - it was actually slower by almost 15% in the Unigine Heaven benchmark. I wonder if this has to do with the card not running at full speed in performance level 3 - the Nvidia control panel reports a 549 MHz graphic clock, which is way too low for this type of card. I am using driver version 304.37.
