probably very stupid question, but i need to ask, i play bf4 on benq xl2420z, with gtx 980 from gigabyte, and it has problems to maintain 120/144fps in game , sometimes fps go down to 80/90 fps, i play at 1080p with medium or high preset, so question is, is 3770 bottlenecking or simply 1 gpu is not enough to maintain this high fps in bf4 ?
