I need help finding and fixing a bottleneck in performance. I have an i7 2600, asrock z87 pro 3, 16gb g.skill 1866mhz RAM in dual channel, 750w evga b2 bronze psu, zotac amp! omega gtx 980, and 3.5tb hdd space of various manufacturers. I get 40-50fps in Borderlands The Pre-Sequel, 60 in city but 20-30 up north in gta v, 40-60 fps in civ 5, 20-35 in AC:Unity. Note that it's at 1080p, all are maxed except advanced options in gta, and 2x AA in all. These numbers are much lower than what the 980 is capable of, so can someone help me? Anything is appreciated.
