personally I think if you have no issues running with your system playing games (low fps or forced to run non ultra modes) I think your pc is pretty damn good.
if your itching to add something new you could go to a higher end video card like a gtx1080
otherwise a faster cpu would mean a new motherboard.

Their nothing to upgrade that makes any big differance for the money spent.
You already have one of the best gaming processors made for gaming upgrading to a i7 6700K would make no differance.
A GTX 1080 at the cost of upgrading is not a big enough change to justify the price.
Keep what you got and wait on the new releases for video cards and benchmarks to come out.
DDR3 vs DDR4 performance really isn't much either. You could maybe go with another graphics card, for SLI, but otherwise there is nothing that screams upgrade now.
