So as for bottlenecking everyone over sells it. I'm running a AMD A10 7860k running at stable OC of 4.2ghz and for gpu I'm running Asus Strix R9 390 w 8gb Vram and I'm loving it. As for the terrible bottle neck I'm supposed to be experiencing? My bud built a new setup last month with same gpu but an i5 6600k cpu, he gets on avg 4-8 more fps then i do on same games, same setting (highest btw). Asus R9 @ $330 and had double the Vram of comparable gtx. His overall build cost about $300 more then mine for 4-8 fps. I like a value. But either way don't be worried about heavy bottlenecking, ur 6300 runs in the 4.2 4.3 area at OC'ing
