I just bought a r9 390x because i got a good deal on it. I have a fx 8230 overclocked at 4.3 which is not running at 100% when playing so its not a cpu bottleneck. The gpu is running at 100% on world of warcraft getting 17 fps on high settings. It looks like the core clock is running really low at like 600 mhz most of the time and will occasionally spike to 1100 mhz. What could the problem be?
