I can't get my 2500k and 7970 to go all out in Bf4. I cut down the AA to 2x. I play on a 27' 1080p monitor. I get 50/60 fps most times and dips into the low 30s. When the shit hits the fan in game with nades, guns, smoke, fire, levelustion or whaterver it is called, go off at the same time ....you will get dipps.
I would guess that you will get overall good results tho. Untra/High mix is more than fine to play. Just cut down on the AA and OC the cpu if you can.
The game is buggy and has lag spikes that have nothing to do with the rig. Just be aware.
