I just got two 660 ti superclocked in sli. However on the highest settings in metro 2033, I am getting the performance of only one of the cards. I read on another forum that a guy with 580's was getting 80+ fps, I am getting 40-50 at the moment. My specs are: SLI 660 ti superclocked, i7 3770k, 16 GB corsair vengeance RAM, and a 700 watt power supply
