I tested this myself already, i had the gigabyte HD7950 paired with a 6300 on a msi board just before i built my new rig and no cpu bottleneck was found, it was a perfect match...the only game in witch the CPU was the limiting factor was a modded skyrim that i was running and it was not by much the card was running around 85-90% load...so unless all you do is play old single-threaded games at 100+FPS, no this CPU will be no magor bottleneck...i tried the FX-6300 overclocked with my GTX 780 and it was still feeding the card to 100% in BF4 and crysis 3.
