Technically speaking, yes, your 750W power supply should be capable to power both your 7970's. Most of your components seem to be somewhat power friendly.

I am unsure however if your power draw is higher than expected due to the overclocking, but I estimate you have at least ~100W clearance after the 2nd GPU, which is way more than OC'ing the CPU & RAM could do.
