So, I currently have a FX 6100 at 4.5ghz. Will I see an improvement if I buy a 8320, and oc that? The games I play are Minecraft, BF3/4, and I livestream and video edit a bit.
I had an FX 6200 at stock and changed to an 8320 (didn't meet my expectations, changed to intel). I saw a decent difference but not that remarkable. Initially I thought it was double; my max FPS was much higher but the average was only about 10% higher.
It will depend a lot on your GPU, and the OC capabilities will depend on your motherboard. What are the models of each?
Yes, the FX 6100 used bulldozer architecture and has very low per core performance, which made them poor gamers. A piledriver based 8320 should offer a decent performance increase, how much depends on other hardware.
