My brand new system build, (AMD FX-8320, EVGA GTX 1070 FTW, 16 GB HyperX Ram) isn't running near as well as I have seen some of the reference cards run on particularly GTA V, im getting 30-60 FPS which seems really low compared to some of the reference card benchmarks i have seen. Im using mostly high settings with exceptions in the grass quality, msaa, and txaa. Any possible reasons this might be?
