Question How much differences does overclock make on i7-6700k?

If your MB supports overclocking, there is no reason you cannot crank up clock speeds 100 MHz at a time, and quickly extrapolate what gains would be made once you see the gains from 4.0 to 4.2, and to 4.4 GHz, etc...; most did at least as well as 7700K did, with average samples hitting 4.7 GHz with little effort.
