Introduction
Hello, community. Today, I pose a question about two very different CPU's. I am attempting to decide between the Intel Core i7-5820K, and the Intel Core i7-6700K.

i7-6700K - (https://ark.intel.com/products/88195/Intel-Core-i7-6700...)

i7-5820K - (http://ark.intel.com/products/82932/Intel-Core-i7-5820K...)
Comparison - (http://cpuboss.com/cpus/Intel-Core-i7-6700K-vs-Intel-Core-i7-5820K)

PC Statistics:
PCPartPicker part list: https://pcpartpicker.com/list/2PC4Ps
CPU: Intel Core i7-5820K or Intel Core i7-6700K
CPU Cooler: Cooler Master V8 GTS 82.0 CFM CPU Cooler
CPU Cooler: Thermaltake Water 3.0 Riing RGB 240 40.6 CFM Liquid CPU Cooler
Motherboard (5820K): Asus X99-DELUXE II ATX LGA2011-3 Motherboard
Motherboard (6700K): EVGA Z170 Classified K with Intel Z170
Memory: Corsair Dominator Platinum 64GB (4 x 16GB) DDR4-3200 Memory
Video Card: EVGA GeForce GTX 1080 8GB CLASSIFIED GAMING ACX 3.0
Power Supply: Corsair 750W 80+ Platinum Certified Fully-Modular ATX
Optical Drive: Pioneer BDR-2209 Blu-Ray/DVD/CD Writer
Operating System: Microsoft Windows 10 Pro OEM 64-bit
Monitor: Asus VN289QL 28.0" 1920x1080 60Hz Monitor
Other: Cooler Master MASTERCASE MAKER 5t ($250.00)
Notes: I have 3 different CPU coolers as back-ups in case one fails.

Usage
I will mostly play games ranging from CS:GO to COD to Ark: Survival Evolved. But I will also have programs like skype open 24/7. I would have, on average, 20 to 30 Chrome tabs open at any given time. Finally, I will be starting development of an Indy Game I am working on using Unreal Engine. What I need to know is what CPU will handle this best? I know the 5820K has 2 more cores, but it also has a lower base frequency. So in the long run, which one is better? Thank you for your time.

The only reason to use a 5820k is not for its cores, they will do very little for you, but rather for its LANES.

Your lack of mentioning of PCIE lanes at all tells me you may not know much about how they work...

Long story short, 6700k has 16 PCIE lanes available. That is enough room for a single GPU, or a Dual GPU running at x8. But NO MORE. You can't use TWO GPUs, AND other devices - not enough lanes.
You can use ONE GPU and other PCIE devices, as most GPUs can run at x8 just fine.

If you don't want to do SLI, and you don't want a bunch of extra PCIE devices then there is absolutely no reason to pay huge mark up for the 5820k. None at all.

Again, the only reason to use a 5820k is for added lanes. It isn't much better than a...
