Joining the PC Master Race, What Parts should I buy?

[JCMsergox]

Alright, so obviously you all read the title, so I need some help with my build. I am a former console gamer making the jump over to the "master race", and also a build I can use to record at a good graphics setting, resolution, and framerate to grow my YouTube channel. And I also want the build to play modern games such as GTA V, Overwatch, and Battlefield 1 off-camera at High-max settings and still get at least 70FPS

MAX BUDGET: $1500

I already have a small list of things that I want in it, with attatched shopping links.

Two Gigabyte AMD R9 380's as the GPUs. (2 Seperate GPUs) http://www.newegg.com/Product/Product.aspx?Item=N82E16814125793&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Video+Cards+-+AMD%2FATI-_-N82E16814125793&gclid=CjwKEAjw7e66BRDhnrizmcGc8VcSJABR6gaRKQ5lQq6NqxG9SJOxJQnjwXJh1_SXl1tqrUUwh8gELRoC0Lbw_wcB&gclsrc=aw.ds

Intel Core i7 6700k CPU. http://www.newegg.com/Product/Product.aspx?Item=N82E16819117559&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Processors+-+Desktops-_-N82E16819117559&gclid=CjwKEAjw7e66BRDhnrizmcGc8VcSJABR6gaRZDDyLsrVMw7AWcnlXNzQLvXGy3DgrfMH1xiKqflXexoC6Czw_wcB&gclsrc=aw.ds

And the last parts are some kind of 1TB hard drive and, under my friend's recommendation, a 3-GPU slot case.

That friend is helping me with the building process once I get all the parts built, but he got a pre-built gaming PC that he upgraded over time.

So my main problem is that I don't know what kinds of parts to buyvfor the GPU and CPU I want in my build. I am fairly unknowing about computers, so I need to know what kind of motherboard, colling system, power supply, etc. will support all this, and the best place to get a good deal on it. Thats what I need your help on, so leave your replies down below!

Thank you all for your help.
