Question / Help Building a streaming computer need help on the build

[Tm0]

Hi friends. First off, if this is in the wrong section or anything, please feel free to move it, I am sorry, I just thought this is the most relavant place. Next off, I'm building a computer, in which I want to stream for amateur and collegiate leagues of many esports. Now, I don't know 2 craps of what is needed for this type of setup. I have this worked out, from some twitch guidelines, but since I am going to try to to use OBS as my primary streaming system I guess that is what I should focus on right?

I was thinking the following:
CPU: Intel Core i5-4670K http://www.newegg.ca/Product/Product.as ... 6819116899
Motherboard: ASUS MAXIMUS VI HERO http://www.newegg.ca/Product/Product.as ... 6813131989
Memory: G.Skill Ripjaw X (8gb) http://www.newegg.ca/Product/Product.as ... 6820231445 OR 2 of these http://www.newegg.ca/Product/Product.as ... 6820231666 I'm not sure if 4x4 would be better because of threads or not. I'm not to clear on the concept.
Not sure what's a good Nvidia card these days. I've been sitting on my 550ti for too long.
Was juggling between the following for cases http://www.newegg.ca/Product/Product.as ... 6811139025 http://www.newegg.ca/Product/Product.as ... 6811146070 http://www.newegg.ca/Product/Product.as ... 6811133212

Edit: Total price before video card 678
But I'm concerned about sound. I might reuse my Fractal Design Artic White because it's so quiet.
Excuse any mistakes, I whipped this up quickly. Again if you have tips on hardware for streaming, I'd love you forever

I'd say get the best CPU you can within your price range.

What about the differences between 4x4 ram (More for each thread) vs 8v8?

More for each thread? Huh? I've never heard of that being a thing, where did you hear that?

Less sticks is usually preferred because you're using less power and it's a bit easier on the memory controller. Supposedly a tiny bit faster too, but I doubt it would be enough to notice. If you plan on overclocking at all, I would absolutely recommend going with fewer sticks. Less variables you have while overclocking, the better.
