Hi I am building a computer for the first time and I didnt want any bottlnecking so i was either going to buy an i5 3770k or an amd 6 core cpu(i forget the name). With that being said I wanted to also buy either a evga gtx 680 signature sc or a 660 superclocked. I wanted to know if any of these graphics cards would bottleneck the cpu(vice versa).
