This issue is not mine, but a friend of mines. He just bought Gigabyte Radeon Rx 460 Windforce OC 4GB graphics card for his computer and new 350w power supply for his computer, and when he tried to play games through it he gained no FPS improvement. I think it's the power supply as I think he should have gotten a better one, but I don't really know. I also do not know his other computer specs except that he has 8gb of ram, but I can get them later if need be. Any help is appreciated.
