there will be no bottleneck at any resolution the processor is a very good one do not worry about it
but make sure u have a good psu
you do understand what a bottleneck is don't you? He wants to know if his cpu can utillize the 780 to its best. I would say no. most people in the market for a 780 would have an overclocked i5 or i7 K edition to get the most performance from a 780. If what your saying is true, you would get no extra performance from anything better than a 3450 with a gtx 780, which is BS. I'm not saying he will get poor performance, he will get great performance. But you could pair a gtx 770 with his cpu and not have a difference in fps (at 1080p), due to the cpu not being able to push it to its max.
