Hello, I'm currently running an apu along with my r9 270x. I'm experiencing some terrible fps since the apu is pretty bad. Even clocked at 4.4 ghz. Anyways. With Xmas coming up. I'm looking to get an r9 390. But I need to know what CPU to get. First off, I know Intel would be better here. I have an Asus a88x-pro MOBO and I don't really want to go through the hassle of rewiring everything etc. I want to know if i should get an Fx 8350 then get the appropriate fans (no water cooling) in order to over clock it. As well I need a new psu for this. Please feel free to tell me what I can buy with 400$ in order to make the r9 390 work. Thanks
