i have the EVGA Superclocked version of the 780, and running BF4 ultra (conquest large maps) on +100 fps all the time. and i believe you can get an average of +90 fps without even OCing the card.
He is using an APU though, and from what I've heard, BF4 taxes your CPU quite a bit. I have no idea what frames you should be expecting though.
