CPU: Intel i7-5820K
i would go with the cheaper 1150, they are both 4-core and the 4790k can possibly perform even better, for less.
GPU: XFX AMD R9 Fury X (purchased)
Hard Drive: Samsung 850 Evo 250GB SSD
good
RAM: Corsair Vengeance LPX 16GB (4 x 4GB) DDR4 2666
good
PSU: EVGA SuperNova 750W GOLD
excellent
Optical Drive: LG 16x Blu-Ray Burner Rewriter
do you need this?
Network Adapter: TP-LINK Archer T9E AC1900 Dual Band Wireless PCI
no, you dont need this.
Sound Card: ASUS Xonar DSX
i don't think you need this, some Hi-end people say you do, but i think you don't.
CPU Cooler: Corsair Hydro Liquid CPU Cooler H100i GTX
i dont think you need this. i have an AIO and i think they are not mature yet, performance-wise.
Motherboard: MSI X99A SLI KRAIT EDITION LGA 2011-v3 Intel X99
again, i'd go with 1150. why pay extra for a 4-core with slower clocks?
Case: Corsair Obsidian Series 750D Performance Full Tower Case
if i recall correctly, this is a huge beast and quite expensive, for custom water loops. why not a gorgeous Fractal Define R4 or R5? (cheaper too ?)
