If you already own one 7970, then there is no point in switching to a 770. Unless of-course you want some Nvidia specific gaming features (Advanced Physx, 3D vision with light boost, CUDA) e.t.c.
One would think that the 7970 should be much much better than a 770, considering it has
1, 50% more memory than a 770 (3,072 MB vs 2,048 MB)
2, 18% better floating-point performance than a 770 (3,789 GFLOPS vs 3,213 GFLOPS)
3, 18% higher memory bandwidth than a 770 (264 GB/s vs 224 GB/s)
4, 33.3% more shading units than a 770 (2,048 vs 1,536)
5, 50% more wider memory bus than a 770 (384 bit vs 256 bit)BUT
The 770 tops it in A LOT of game benchmarks, and it's a well borne out fact. Firestrike is not a game mister, and at the end of the day, 99% of people buy GPU's to play games, not run benchmarks to get numbers that don't apply to gaming at ridiculous clock speeds that won't last 15 mins playing bf3
For benchmarking, i'll recommend the 7970 over a 770, but for gaming. 770 All the way, because it obviously offers more..... Just my opinion.
