GTX 600 cards have boost technology meaning they have automated dynamic overclocking that is effected by heat, power draw and load. The reason one card is running faster is either A: its factory overclocked B: its boosting higher due to it running cooler (or having a better binned gpu).

Some times SLI can actually be a bitr quirky and say the top card is number 2 and the bottom card is 1. Temperature is the easiest way to tell as the top card should be hotter especially under load.

So in order for us to help we will be needing your temps, your stock clocks and boost clocks. Then we can look into getting some OC going.

Well core is 954 and boost is 1033. My temps jump fast but with fans at 80 they never go past 70c. I have a nzxt switch 810 so air isn't in issue..
