The two GeForce GTX 760s in 2-way SLI mode easily beat the single GeForce GTX 780 in each of the three test scenes. The overclocked Zotac is hardly any faster than the reference GeForce GTX 760 although the difference in their frequencies is quite large (+13.4%). The next benchmark, Unigine Valley, shows the same picture.

Total War: SHOGUN 2 – Fall of the Samurai
The GeForce GTX 780 is just routed by the cheaper SLI tandem built out of two GeForce GTX 760s: the gap is 21% and more! The SLI configuration has high bottom speed, so the game runs smoothly on it. Its efficiency is over 90% compared to the single GTX 760, reaching 96% at the hardest settings. As for the Zotac GeForce GTX 760 AMP! Edition, it is 3 to 6% faster than the reference GeForce GTX 760.
We have almost the same results in Battlefield 3 as in Total War: Shogun 2:
Sniper Elite V2 Benchmark
We’d praise the performance of the 2-way SLI tandem in Sniper Elite V2 if it were not for the rather low bottom speed. As for the average frame rate, the two GeForce GTX 760s are 82-92% faster than the single such card and outperform the GeForce GTX 780 by 25-30%. The Zotac is 4 to 7% faster than the Nvidia.
