I recently upgraded my graphics card from a GTX 560 Ti to a RX 580 4gb and I'm getting less FPS, around 30FPS less in Overwatch. I know that my CPU is bottlenecking my GPU but shouldn't there be at least some FPS increase with the same graphics settings? I'm currently playing with an AMD FX-4200 with 8GB of 1600MHz RAM. I would like to find a solution to this problem.
