I just recently upgraded my Radeon 6950 to a R9 290. Much to my dismay I'm getting the same performance as my 6950. Assassins Creed 3 is running at 20 FPS on max settings. Crysis 3 is running at about 10 FPS at max settings with AA disabled. There is no way this should be happenning. This is my set up:
i7 2600k @ 4.5 ghz
16 GB ram ripjaws 1600 DDR3
XFX Radeon R9 290
Everything should be fine... But is my Power Supply causing my R9 290 to perform poorly? This is my power supply:
I bought this PSU in 2011 because of the price and advertised power. Does anyone have any idea why I am getting this type of performance?
