This build is actually my workstation and my gaming rig. It's actually running every games possible at more then enough FPS(60+) even in 4K. I'm using the 2x 10TB from seagate in Raid 0 and the system is overclocked around 36% ~ 40% depending on my feelings. I've been doing benchmarks on 3D Marks with it and I broke 4 hall of fames using a single card and both in SLI.

I decided to go with the I7 6950X since the I9 Lineup wasn't annonced yet , but I'm still pretty happy with the result since , it's really stable around 4.1Ghz to 4.3Ghz and was pretty easy to reach 4.5Ghz.
Issues with the build ? :
Mainly about RGB , since there is a lot of RGB headers that were not really compatible together. Like for the corsair fans that cannot use the same hub and controller and each AORUS cards and the sli bridge running on RGB Fusion from Gigabyte and the mobo and the case that runs on ASUS Aura!
The case was a bit small for all the cables , which I'll probably upgrade to cable mod custom cables* in the future. That's why I gave up on the cable management in the back of the case since it was really a mess.
The 2 1080Ti running in sli got a real performance boost in almost every title using the high speed bridge made for those cards. It's totally stunning even in 1080P.
Pretty Interesting airflow for a huge setup that fit inside a small case like this one and no heat issue so far.
