At 1080p, that PC should run BF4 at max settings at 60fps.
I have a GTX 660 (and an i5 3470) and I can run BF4 on max settings (except for MSAA) at 1080p at 60fps.
Considering the GTX 760 is a bit more powerful than my card (and the i5 4670 is better than my 3470) you should be able to max it.
I would also imagine that Ghosts will be maxed, as it's not exactly a taxing game. Not sure about Titanfall though.
