I have a asus h110m-r and an i7 7700k. can overclock on this board
The H110 series of motherboards doesn't support overclocking. Z170 or Z270 would. But it's not worth upgrading the motherboard just for that. The motherboard is basically irrelevant to gaming performance to the H110m-r is as good as the next in terms of your framerate.
I vaguely recall you posting your prospective spec a while ago and ignoring the advice you got.
So I offer the above advice with some trepidation...
