Okay so since the forums on this amazing site helped me out so much, i figured i would post first build. :)
(Now I built this pc 6 months ago, back then I didn't know about the new graphic cards coming out)
Looking at the inside pictures I can already hear you thinking "That cable management could be better/sucks" but remember it's my first build and I really did try my hardest to tuck all the cables away as best as i could have. The Fractal r5 case in combination with the NZXT kraken X61 made it kinda impossible to cable manage those kraken cables. But even with those cables there I still get really low temps when idle and under load so no problem there.
Anyway enough about that, on with the parts!
i7 6700K : I could have bought the i5 i know, but money wasn't really a problem so I just went with the safest option. I also went with the watercooling bacause it's quieter and looks way better.
MSI Z170A gaming M5 : Now this motherboard is great, but I did have a problem with the Killer Ethernet NIC that came on board with the motherboard. The NIC made streams lag, downloads were really slow etc.. I did update the driver but that didn't seem to help. So thats why I added a wireless adapter from TP link to my system, bypassing the killer ethernet NIC. This completely fixed my internet problems.
Corsair Vengeance 2x8GB : Corsair is always a solid choice so nothing to say about that :)
Samsung 500GB SSD : Chose this for my OS but also for some games that usually load a bit slow, like GTA V for example.
1TB HDD : Can't really go wrong with HDD's ;p
MSI GTX 980 Ti : At the time, this was the best option for me, this gpu is a beast, runs very quiet and cool!
Fractal r5 : I was planning on placing my desktop right next to me, so I really wanted a quiet case, this one does an excellent job at that. But because the case is a mid tower, I couldn't really cable manage the watercooler cables.
EVGA 850W PSU : So I wanted a psu that could manage dual graphic cards, if I ever want to add another 980 Ti. 850W is a good option for this.
Optical drive: I don't want to download all my games, especially the bigger ones.
Corsair AF140 Red : Decided to add another fan to my case, though i am still waiting for a fan cable splitter. When i have the splitter i will add my other fractal fan to the front of the pc.
Acer XB271HU monitor: Aah, the reason why I just posted this build now, wanted to wait untill i got a fitting monitor :). This display is a beauty. 166Hz , IPS display, G Sync and 1440p. I'm in love with this thing :)
Thats it, thanks to all the people on this forum for all the help!
