Hey everyone, I just wanted to let you know that I'm now successfully using gpu passthrough and it's great! Thanks so much to everyone who took the time to help me out. Unfortunately, I was never able to get it to work on Arch. I decided to give a new distro a try for the first time in 5 years (Fedora 23). I had forgotten how nice it is to have everything curated for you with secure configurations by default. I followed the instructions in the blog and it worked on the first try.
