GTX 760 Advice

Thanks Everyone for the Help!! I was thinking of getting another 8GB of ram and upgrading the CPU to the Eight-Core by AMD.

I have an AMD FX-8350, which has a stock speed of 4.0 GHz (4.2 Boost), and it is very good for it's price. It doesn't beat Intel in performance, though. I also have 16 GB of RAM. Unless you are running a whole bunch of programs in the background, the extra RAM won't really help in GTA IV. 

For reference, the GeForce Experience program recommended that I run GTA IV with highest settings, except 75 on all the slider options and only high on shadow quality when I had a 660 Ti. I now have a 780 and it still recommends the same settings. I'm guessing it's my processor that is making it decide that it's best to keep those lower. Or it could just be because they know how badly optimized the game is. Of course, that program isn't perfect because it recommends that I run Arma 3 on almost all low, but extremely high visibility. That results in a huge framerate loss simply because of the visibilty, so I use the settings recommended by Arma which is much better (and much higher quality). I may have went a little off topic now...
