Complete $3000 Canadian PC Build

I've designed a complete system build for video editing/rendering and some content creation, as well as heavy gaming, this build includes:

-A desk
-A chair
-1 IPS panel monitor
-1 TN panel monitor
-A good mechanical keyboard
-A great pair of headphones

But, maintaining all these features, I invite you to rate and make suggestions on my soon to be build, and even design build of your own if you with, but, enough of my rambling, here's my designed build:

I personally like the EVGA SuperNOVA 850 G2 over the Corsair unit because it uses better components and comes with a ten year warranty.

If you aren't planning on travelling with your headphones, you could save a bit and go with just the M50s instead of the M50Xs. Both get uncomfortable after about four hours of use, so keep that in mind.
