i think everything has been covered by luciferano, a few quick things though. First, i should have clarified about the power consumption i meant just the cpu's when referring to that power figure, as the 7770 will draw the same on both boards. Also i dont know if you realize this but you can only hybrid crossfire the a10 with a 6670 max, so the superior cpu (i3) wins. If you even want to make it a contest, as i said earlier, you would need to get a 6670 and hybrid it and then overclock the a10s cpu, all of which leads to much greater power consumption at the same price point and still isnt even as good a performer as the i3/7770 (they trade some blows atleast though).
