I am about to build a new gaming streaming pc and i am going to stream mainly (Cs go) with 144hz monitor but i am gonna play heavier games also (without streaming) so i wanted to know is it better to buy an i5 8600k and overclock it or an i7 8700 without the option of overclock.(The gpu is gonna be propably gtx 1060 is it gonna bottleneck any of these cpus?)
