Installing MSI R9 380 into a Mac Pro Mid 2012

Whats up guys, to finish off this series I present the installation of the MSI version of the R9 380 graphics card. My current system is a Mac Pro Mid 2012 Quad Core. While using Final Cut Pro X I&been having issues with frames being dropped and lag. At Better performance and optimal quality. (4k or 1080p, and I refuse to use Proxy) I went to local shop and was told this card would be a huge upgrade and will work even though its not supported by MAC. After a week of testing, its work perfectly in Final Cut Pro X. I have notice the performance boost. Only in Pro Tools 11, the video engine has timed out every time. If I can&find a solution to this issue, I might put back the old 5770 whenever I work in pro tools. The track playing during this video is a composition a friend of mine did, which I had mastered for him. There aren&any links to this track, sorry.
