Extreme 4K Gaming build, advice?

Hi everyone,
So recently I joined the Digital Storm forums and have (tentatively) decided on a rig from Digital Storm, given their history of high-quality custom gaming computers and excellent customer service. I've decided on this build, which will be mainly used for 4K gaming at maximum settings, light video editing, and some streaming. I want it to be as future proof as possible, to play the most demanding games at 4K at maximum settings for the next few years with ultra smooth frame rates.

Also, is it possible to (special order) change the GPU to Quad EVGA Geforce GTX Titan Black Superclocked? If not, I will be overclocking the GPU to around 1200MHz-1300MHz core per card for the maximum extreme performance possible.
Thanks!

For a purely gaming PC, I wouldn't go with the X79 platform. I would go with the Asus Maxiums VI Extreme and the new i7-4790K with 4GHz base clock and 4.4GHz boost clock. These are supposed to hit retail by the end of the month. My understanding is that Asus is working on a BIOS update to make that motherboard work with the Devil's Canyon CPUs. If you go the Devil's Canyon route you would want to go with a DDR3-2133C9 or DD3-2400C10 for memory since those are the Haswell sweet spot for memory performance.

Asus has not announced a Maximus VII Extreme motherboard today at their Computex press conference earlier today. From what I read the "Extreme Team" is working on an upcoming platform.

OK so to be clear and like I said earlier on, I will be doing video editing (not professional, merely as a creative pursuit), Photoshop, After Effects, and (possibly) streaming. Also, 4K gaming. So should I go with i7 4960X instead of i7 4930K? The CPU will be clocked to 4.8GHz-
5GHz. As for the RAM. Should I special order Quad Channel (4x8GB) Corsair Dominator Platinum 32GB 2400MHz RAM? Or should I stick with the 16GB 1866MHz Corsair Vengeance Pro RAM?
Thanks,

If you're doing 90% gaming and 10% video work, the Z97 Devils Canyon will likely perform better than the 4930K. Even in my own tests, most games would give a 1-5 fps increase with the 4770K over the 4960X.

Originally posted by Annihilated Well, X79 seems to be the only option in this case because the Rampage IV Black chipset has a PLX switch, so the 4-way SLI Titan Black setup can be run in x16-x16-x16-x16, which is simply not possible with Z87 or Z97 due to limited PCIe lanes.

Very true, if you are going with a 4-way setup, X79 is the way to go.
