Yes BF4 takes a bigger toll, in numbers yes, but realistically in your setup you should be able to do much better then that. You might want to turn off OC on the GPU and check those numbers (install MSI Afterburner to keep tabs even during 'intense combat' on your FPS, Temps, etc.).
I would run malwarebytes on a full scan, because you should be performing much better on BF3. Also do a full scan with a good AV system (don't rely on MSE it sucks, try Comodo, AVG or Panda.... AVAST! was compromised so I don't recommend them anymore). Then make sure ALL Windows Updates including OPTIONALS are run (Except BING). Then lastly run SlimDrivers to ensure ALL drivers are up to date (amazing what little parts DON'T get updated sometimes)
