How much of an increase will there be for gaming systems for the i5 6600K vs i7 6700. I love top end games that have high graphics. Witcher 3, Assassins Creed, Crysis 3, Far Cry 4 etc... This will be running on an ASUS Hero VIII and some GTX 970. Memory will be 16 gig of DDR4 as well. Unsure of the clocking speed to pick on that yet but lets assume whatever system is configured both will be identical so we are comparing apples to apples.
