I recently built my first gaming pc, of which I had a tight budget but I wanted an rx 480 I found on sale newegg for only $200. When I put it togather, the fx 6300 was bottlenecking terribly, but since overclocking it from 3.5 ghz to 4.5 things have gotten better, but not the performance I would see on a benchmarking video with, say, rx 480 + i5 6600k. I am wondering though, is my cpu still holding back my GPU? In games like just cause 3 I have stuttering, although I dont know if this is because of my 8gb of ram, but in most games my GPU load is 100% and cpu around 50-80%. I just dont really know enough to officially answer this myself so someone please tell me.
