A few years ago I built my first pc. It runs and i7-4790k over clocked to 4.5 ghz, a gtx 980 over clocked as well, 32 gig Corsair dominator platinum ram at 1333 MHz. I have 3 27 inch Aoc 1080p monitors. I’ve noticed that on some games the graphics tend to lag a little, would this be because of the cpu or gpu? Thanks!
