Check "Vertex Streaming Hack" in Graphics > Hacks. It's a free speedup on Nvidia's drivers that gets rid of a *lot* of GPU driver overhead, thus reducing CPU usage and CPU-GPU transfer latency. (You can also use a current development build of Dolphin that does it by default via an official OpenGL 4.4 feature instead of with a dirty optional hack, as long as you're running recent drivers – whatwasit, 331.20 or so?) I find it hard to believe that you can be CPU-limited with a 4670K at 4.4 GHz (that's the most ideal CPU for Dolphin, plus that's a higher overclock than most would recommend/need), so I'm gonna say it's CPU-GPU transfer latency that's bottlenecking you.

You'll also want to make a profile for Dolphin in the Nvidia drivers, setting it to "High Performance" for the GPU choice and changing the Power Management Mode from "Adaptive" to "Prefer Maximum Performance". This keeps your GPU from repeatedly trying to downclock itself while running Dolphin – the way Dolphin uses OpenGL/Direct3D is unorthodox enough that GPU drivers' power-management algorithms tend to fail on it and reduce performance. (Theoretically, Dolphin could request this setting automatically since Nvidia has an API for this, but their library for it isn't GPLv2-compatible, so Dolphin can't legally use it.)

After you do all that, you can probably turn up the AA/AF further. I'd also recommend you use "Auto (Multiple of 640x528)" or 3x/4x as your Internal Resolution – there are more than a few games that don't enjoy rendering at something other than an integer multiple of the native resolution, and your GTX 780 can surely handle 4x with some AA. Dolphin isn't really that GPU-intensive, anyway.
