I currently have the processor above with a 7870. I know i should have gotten a better cpu but at the time I had no idea what I was actually picking out. My cpu is overclocked at 4.6ghz and I am currently (according to MSI afterburner) am getting 100% utilization of my gpu, and I am steady at 100% usage with no fluctuations. So... right now I have no bottleneck. What I want to find out is how bad of a bottleneck I would have if I was to upgrade to a 770 or 7970. I could further overclock to 4.8ghz if necessary to reduce bottleneck.
