Is this a good build for my needs?

[Raven Ocara]

Let me tell you my needs and then I will post the link.
I want to be around $3,000 budget- if it goes over a little it's okay, but not too much over that price range.
I will be using the computer for playing games on ultra settings but I will be streaming on twitch using the best settings that I can. I will also be editing videos and will be editing in 4k quality under adobe after effects and premiere pro. I also plan on doing 3d rendering in the future as well.
I need this computer to last me a long time spec-wise. So the more future proof it is, the happier I am.

Perhaps this is overkill- but here is the rig I wanted to do: http://pcpartpicker.com/p/rnkPWZ

I will add in even more ram and perhaps do a 3rd video card hook up over time. But currently, that's above my budget so it will be upgrades that will need to wait. Windows 10 will come out by the time I get everything together to build this pc- so chances are, I'll end up doing Windows 10 instead.
Basically, need a fast video machine that streams and plays without breaking a sweat. I'll be editing 4k video so I need it to be able to render fast and not worry too much about the program's not responding. Hence all the ram and video cards.

For editing I'd get at least 2TB drives eg WD Blackl or seagate barracuda.

For 2 x gtx970s, just get the evga supernova g2 750 gold psu.

The H240x will come with pre-applied thermal paste.

I din't think you'll need those extra case fans.

Otherwise it should be a great editopr/gamer PC.

With good airflow you can change the case to something less expensive. Also I would go for at least the mid-range Haswell-E six core. Personally I would even go with the octo-core(1k tho). Rendering etc.... I am not to sure about those 970s. For gaming more than good but for the rest of the tasks, my advice Would be 980ti or Titan X.

if rendering is gonna be a big part of usage then i would suggest you go for an octi'core minimum.
yes its expensive, but there is a reason to consider 1 as gpu rendering isnt particularly well supported by render engines.
for instance things like volumetric lights rendered with iray are still cpu intensive even though iray supports cuda.
so an 8 core would seriously help speed things like that up.

personally i would say in this case spend as much as you can on the cpu, as much as you need on the gpu, a decent 750w psu and scrimp every where else to keep it under budget.
3k is quite a bit so should buy quite a bit of performance if. you dont spend half the money on looks.
