I use this for gaming at 4k resolution and for work
cpu is clocked up to 4ghz and I overclock the video cards +180 gpu and +320 mem while gaming. RAM is at the 2800 xmp profile
Besides the water cooling and monitor setup issues I wrote below this build has been amazing. Borderlands 2 looks incredible and GTA V runs at about 40 FPS with mostly max settings (keep in mind 4k). I can also run minecraft :o Also I must say the bios/software that comes with the motherboard is really convenient. I felt like splurging on the best parts money could buy, no ragrets
This was my first time water cooling, I did have two water leaks. One was noticed straight away while filling, I was using crappy connectors between video cards so I swapped those out for something better, and another I discovered a few days later in the reservoir, it was a very slow leak and it didn't do any damage as it only got a small puddle on the bottom of the case. Apparently you need to put the screws back in after swapping out the plate inside the reservoir as I did not want the "waterfall effect". I am still paranoid about it now though and check the level every day. Also its been about 7 months and the pipes are turning green-yellow I should probably replace them at some point, the water in the reservoir looks clear though. Also I think my loop could be more organized with a better drainage system. If i want to drain I will have to actually unscrew the bottom radiator to get the drain valve actually sticking out of the case so that was just poor planning on my part. Right now I am using strong sticky velcro to hold the reservoir and pump in place as I didn't want to drill holes. It isn't ideal, but it does hold well enough.
Another issue I ran into was setting the monitors to use the correct display port version, they turn off almost immediately without input detected, so I actually had to hook up a hdmi cable to my laptop just to get the monitors to stay on so I could change the display port setting so that it would actually work with the video cards
The part list here is what I ended up actually using, wasted more money on other things that ended up not being used. Also stuff is a lot cheaper now half a year later so I modified the prices to be what I actually paid. I have another pump and triple radiator that I don't need if anyone is interested. I had returned a sound card and a different keyboard as well, the much better k70 is amazing.
