So Im planning to build a pc, which i will mainly use it for dev and gaming in free time, my main components will be:
CPU: INTEL 8700K
GPU: GTX 1080 msi or gigabyte?
SSD: 860 EVO
RAM: 16GB 3200MHZ
MOTHERBOARD: should i go with msi or gigabyte whixh one is better?
PSU: 650W or 700W deepcooler?

Also for the cpu cooler do i get water colling or a standard cpu fan?

P.S: i plan to overclock the cpu and gpu at some point.
Also whats your opinion on the rgb lightning gpu and motherboard, and is there point in getting a mobo with sli support (is it work buying second gpu at some point or better upgrade the existing)
