Ank34 :
CPU : i5 - 7500
GPU : 1060 6GB
Mobo : h170 or h110 (i will be overclocking with a hyper 212 evo)
PSU : 620W
HDD : WD 1 TB
RAM : 16GB (4x2 + 8x1) {will this affect performance}
I'm coming from an existing build ( fx-6300 and r9 270x)
2 problems with that build, no 1 problem, you need a K series CPU to overclock, and numver 2 problem, you need a Z series motherboard to overclock on, and unless you already have a Sky Lake CPU, then you'll also need a Z200 seriess board as Z100 or H100 etc doesnt come with Kaby Lake support out of the box.
So the rest of the specs are OK but you need an i5 7500K and a Z270 motherboard to overclock and for your CPU to even work.
