I'm going to build a new PC quite soon, but I need some help. I already have the graphics card I'm going to use, a Gigabyte GTX 1070 G1 Gaming. My plan was getting an i7 6700k as CPU (Mostly gaming, but also maybe streaming / other more CPU intensive tasks), but outside of that I'm a bit lost. I was thinking of getting 16GB (DDR4) memory since it's not that expensive and I'm occasionally hitting the 8GB-limit on my current PC, so I might aswell. I want to overclock the 6700k. As for storage, a 500GB SSD, I still have a HDD lying around I can use if I need more storage. Probably not gonna get a DVD drive since I still have one I *could* use if necessary, but I'm pretty sure I used the DVD drive on my current PC literally once.
However, I have no idea what a good motherboard / RAM brand / PSU / case / SSD / (am I forgetting anything?) would be. I don't have a specific budget, but I don't really want any special features, just decent prize/performance overall; basically not spending more than necessary, but not cheaping out on anything. As for size, I'm assuming an ATX? motherboard/case, since the 1070 is quite large (~280mm IIRC).
So basically:
GPU: GTX 1070 (already have it)
CPU: i7 6700k (with a decent cooler)
RAM: 16GB DDR4
STORAGE: 500GB SSD
the rest: ??
I'll buy it from a dutch webshop, but I don't know which one specifically (I usually use this to find sites to buy hardware), so I suppose the german pcpartpicker is fine for me, I'm guessing the prices will be really similar.
Thanks in advance!
