I recently upgraded my GTX 760 to a 980 Ti, and my processor to a i7-4790k. Most games see to run better, but Sins of a Solar Empire Rebellion and Total War: Rome 2 actually run worse. I have checked my GPU drivers, reinstalled both games, and checked my connections. My power supply is 850 W, so it should be enough. How could upgrading to a better GPU and CPU result in worse fps?
