So basically my question is "Is the CPU good for this 4K build?"

Motherboard: MSI X99A Gaming Pro Carbon Intel (Socket 2011) DDR4 ATX Motherboard

CPU: i7-6850K 3.60GHz

RAM: Corsair Vengeance 32GB (4x8GB) DDR4 2666MHz

Graphics Card: Asus ROG STRIX GTX 1080Ti SLI

M.2 SSD: Samsung 960 EVO Polaris 250GB for system operations

Solid State Drive 1: Samsung 1.0TB 850 EVO SSD 2.5''

Mechanical Hard Drive 1: WD Black 2TB 7200rpm

Power Supply: Seasonic Prime Platinum 1200W 80 Plus Modular Power Supply

Soundcard: Asus Xonar Essence STX II 7.1

I'll appreciate any information regarding the setup that could be changed but I just want to know if the CPU is good for 4K or if there's something better :)

As output resolution increases, the GPU load increases almost exponentially, while CPU load increases logarithmically. My 4790k is never over 30% load when I'm pushing my 1060 up into higher resolutions beyond native 2560x1600 when running GPU synthetic benchmarks and torture tests, so at 4k, I bet the newer i5's and greater or R5's and greater can handle 4k just fine. Accounting for performance overhead for CPU-heavy games like GTA5, WD2, and Mafia 3, and CPU-murderers like Planetside 2, H1Z1, and that new player unknown thing, I personally think that anything over the normal 4c/8t i7 is kinda overkill. Unless you plan on streaming internally in H.264 without a capture card. With that kind of budget, what's stopping you from getting a...

Unless you plan on streaming internally in H.264 without a capture card. With that kind of budget, what's stopping you from getting a Ryzen7 1800x, an X370 motherboard, a beefy AIO like a Swiftech H240x2, or getting a Z270 motherboard, a 7700k, and a full system custom water cooling set up? EK makes full-coverage waterblocks for the Strix 1080ti.

TL;DR 6850k is overkill for a gaming-only build, regardless of resolution. IMO.

Obligatory YMMV.
Just my opinion.
