I have a EVGA Gtx 960 ftw 2.0, 16gb ram, i5 4690k not OCed. I just upgraded from an i3 but my gaming performance has nose dived pretty badly. I haven't upgraded my mobo yet from the stock Dell 88DT1 that came with. I don't know if I'm expecting too much when I say I just want a steady 50-60 fps. What's happening? Bottlenecking? Is my mobo holding me back? Should I switch back to my i3?
