Started with a 4790k but ended up going with the 5930k for the 40 PCI lanes. I doubt adding a fourth card would be worth it at this point but I plan to in the near future because the 980 doesn't have long for this world as a top performer with what I hear it will be dropping on the market this fall.
The EKWB Cooling is amazing. Hit 89c running Prime95 but that was the Cap and that's only because the water hits the cards before the CPU. If it went the other way around I'm sure it would be far less. The cards capped out at 52c at the highest point in any given test.
(Warning you might Cry) I used to joke with my father about the power requirements of computers and he said "just build a boiler powered one and stroke the fires." He said this because he spent about 10k on a boiler setup that heats his house and floors. I started planning to build this after he found out he had late Stage 4 Cancer in January. I took over his business shortly thereafter and my time was sucked up for awhile during the transition and his treatments. Now I didn't get a boiler going but I did get a water setup that looks somewhat like a boiler. My dad has been hallucinating while I lay here in a cot next to him in the hospital but I took a video of me running my setup and he laughed quite a bit and said "Holy cow you got the boiler going!" I love you dad...

This is effectively 13 Million pixels which is over 1.5 times that of 4K
I will take legitimate questions.
Edit: My father passed away a few days ago. I tinkered more and added the fourth card/new board. Waiting on some custom bolts to come in and I'm adding 8 more fans. It sounds ridiculous and it is but I'm sick of cranking my A/C every time I play TW3 or BF4.
EDIT: THIS BUILD WAS REPLACED WITH THIS https://pcpartpicker.com/b/FzccCJ
