As defaults for i7 8700 with K , it has little big frequencies then i7 8700 without K. But will i7 with K it work on such frequencies as default or i need to setup something in bios? If i buy i7 8700k and will do nothing with setups in BIOS , how will it work, will it be better then i7 8700 ( without k)? If i need setups , what should i set in bios to make it run on 4,70 GHz as discribed in specification? As i saw also i will need good cooling with k anyway, also without overlocking, which one to pick be quiet, noctua, as rock, or something else? Also if i gonna pick RAM `G.Skill Trident Z 32GB DDR4 32GTZ Kit 3200 CL14 (2x16GB)` - it seems i need to enable some XMP in bios? Will this ram speed cause CPU frequency if i do not overlock the CPU?
