Hi, I'm a little out of the loop since I built my system, would a i5-2500k (socket 1155) bottleneck a GTX 760 @ 1080p on a single monitor? And will I notice a nice boost in performance over a 560 GTX? Or would a processor upgrade be necessary to take advantage of a GTX760? I really can't OC the CPU as I have a stock cooler and it's in a HTPC environment where fan noise would be an issue.
