I just spent over $500 dollars upgrading my computer from the 2012 FX 8350 to the 2015 flagship i7 6700k, and in the first game I test, Assassins Creed: Unity, my performance was identical. Not even 5 fps difference 45 fps AVG with Fx 8350 and 47 fps AVG with i7 6700k. What is happening what possible reason could there be for the performance to be identical. Before you ask the GPU is not a bottleneck sitting around 60% usage most of the time.
