A little over a year ago I asked for help here to make a budget AMD build, and it's served me well, but certain games I play (Specifically Path of Exile) Have serious FPS issues with AMD CPU & GPU combos, yet not with AMD/NVIDIA or Intel/AMD. Also, I've been working and I wanted an upgrade anyway.
Current system:

I want to upgrade one of the two parts that will give the biggest gaming performance increase, either the AMD 8320 or the Radeon 7950. I don't want to spend more than 375$, preferably in the low side of the 300-400 range, after shipping and rebates.
I can either
1) Upgrade the GPU
2) Upgrade the CPU, and the motherboard with it
I don't have any major issues with the CPU currently, although I know the single threaded performance can't match Intel's Haswell/Haswell refresh series. However, I have had multiple occasions in the past three months where the screen suddenly decides to stop working. All fans run, but the screen goes black, or freezes. Sound still works though.. I usually have to restart it. This has gotten me killed twice lately in hardcore gaming, and I'm perturbed. My GPU rises to upper 70s and low 80s (Celsius of course) in intense multiplayer parties. Motherboard gets hot too, but not that high. The CPU rarely goes above 50.
So here's my question: What option will give me a better performance boost for the money, and what specifically should I buy? I already have a Hyper 212 EVO so I can get a non-boxed CPU and save a tad. I will be doing gaming that requires quick response times, including PvP. I will only be running a single 1080p monitor for the next few years.
Yeah, I'm going to have to reinstall stuff. I'm fine with that, I might even go and try Windows 10!
