Xotic84, I've been having these same issues, I went from one GTX 760 to SLI recently, mostly I only play Titanfall.  I was shocked to notice the performance was considerably worse with 2 760s as opposed to one when playing Titanfall, I'm going to start the process you followed in this thread now and try my luck... just curious, when you say you can play Titanfall with max settings do you specifically mean max, like Texture filtering at "Insane"?  and if this thread happened before Titanfall added ambient occlusion support, have you since tried using it?  and how were your results?
 
Thanks!!
