I finally upgraded from old build (i5 2500k and a GTX 1070). I chose the 8600k because it almost matches the 8700k in terms of gaming, and even surpasses it in certain titles. The 1080ti was a no brainer, and there no bottleneck what so ever. I included power supply but I actually bought it from a friend for $80 bucks which was a steal. The FSP 520 case was very nice to build in, there is a lot of cable management room in the back.
