I am asking this question for an update. Lately, with the release of the GTX 1070 and 1080 and also the amazing trailer of Battlefield 1, I was wondering if an i5 CPU still will not bottleneck a powerful GPU at all. I saw a chart and for the Witcher 3 it seemed to matter a lot on which CPU you were using. I will be getting a GTX 1070 when it releases, should I keep my i5 4th gen or upgrade to an i7? Because I know that Battlefield, especially the multiplayer part, is pretty CPU intensive.
