Frankly, I think this'd do you better for much less while still being overkill.. From the benchmarks I've seen, SLI 980s can fight with Crossfire 290Xs but cost less and will eat less power/spit less heat into the case. That and, with OBS at least, the NVENC codec will help in offloading the encoding to the GPUs and keep off the CPU (though that definitely shouldn't matter on a 5930k). If you wanna save more, swap these to SLI 970s
You're definitely not going to need 64 GB of RAM unless you really want obscene amounts of RAMDisks or something (or hundreds of chrome tabs). That, and the kit didn't have a price on it so I don't really know how much it shaves off the total cost
Swapping to SLI 970s brings the power usage way down, but still gave you a top-tiered 1000W 80+ Plat PSU for less than the one you've chosen if you want to throw more in there
The Gigabyte board is tiered higher and should do you better (link has it tiered as one of THE BEST)
Storage options are more personal preference.. I just don't see a use in spending so much on a 1 TB SSD right now and find it better to just get a small one for OS + important programs and large amounts of HDD space for everything else. Furthermore, I'm having doubts as to whether or not the HDD you chose was really even made for what you want to do with it (seems more like something you'd make backups to, as the name suggests, rather than gaming from it)
All in all, this should save you quite a bit and do just as well if not a good bit better
If you want quicker improvements, a NVIDIA GPU + NVENC encoding settings (if your streamer supports it) should give passable results (it runs well enough [read: full speed] on my 2600k + 970 + OBS x64) while the rest of the build comes in (unless you buy it all at once)
Though a saner build with room for another GPU would be more similar to
