I created a list for a first build and im very unsure which motherboard will best suit me. Please keep in mind i am no expert in this field of work so any advice is much appreciated. My build is set this way so that i simply have to upgrade the gpu and cpu. I found 2 boards that seem to be similar but i am clueless as to which will be more beneficial for me. I simply want sli capability (2 cards mainly), some sata 6gb/s and at least 1 sata express, cpu overclock ability (which is where the fuss is at for me) and of course gpu overclocking capability. My main specification is to overclock my cpu, like a i5 6600k in the future. Im very unfamiliar with BCLK but any advice, questions, or recommendations are appreciated. The boards are the (gigabyte ga z170 hd3) or the (asus z170 e) Thank you. http://pcpartpicker.com/list/4jcGGf
