Question Video Editing PC to build with parts already bought

Feb 18, 2019
I have just taken over a build of a PC for video editing and Graphic Creation. The previous "builder" purchased an NVidia K10 Tesla GPU and an 800 Watt Power Supply, and an older Alienware box.

I am tasked with securing the components to make this a fast video editing machine. I'm thinking of a Core i7 8700K, 16GB DDR 4 3000, and a Samsung M.2 500 GB.
I will also have to add a video card, since they want dual monitor support. They're planning to use Adobe Creative Cloud.

My question is... What to do with the K10? It is passively cooled, so there's a problem from the get-go, and does it just work to help process and render, and then output goes through the 2nd video card?

I've built hundreds of systems down through the years, but have never seen one of these cards, much less worked with this one before, so I'm a bit lost.
