I have a really old CPU and GPU. My CPU is Intel q6600 @3 GHz (4 GB ram )and GPU is AMD HD6770. I only play Dota 2. Currently i am playing on low settings @60 fps @ 1400*900 resolution. My fps drops to 30 fps when i play it on ultra. Can u guys recommend me a graphic card which can play Dota 2 at ultra settings minimum 60 fps constant. I dont play any other games and i am not planning to play any in the future. Will the new Rx 460 bottleneck at my current rig?
