I am confused between i7 6700k which uses z170 chipset and i7 6800k which uses x99 chipset. I know that going with i7 6800k and x99 would cost me more than i7 6700k but I am willing to pay more if it is worth it. I am planning to use this pc mainly for gaming. It is like 70% gaming and 30% other stuff. I am planning to get a GTX 1080 for this system. Thank you for your opinions.
