I say to go to original resolution just to see if the speed changes to get the games at fullspeed.
If yes, then that means there's something wrong with your GTX 770.
But if the speed does not change, then you have a CPU bottleneck. You CPU is equivalent to a 3rd gen i7 at 3.3 GHz. Dolphin will only use 2 of the CPU cores though, one for the emulated CPU and one for the emulated GPU. But you should be reaching way closer to fullspeed though on those games.
