Best GPU for Final Cut Pro?

[Meekul]

Hi There,
I am planning on building a Hackintosh which will be used mainly for editing on Final Cut Pro and I'm wondering which GPU will be best for me. I will be editing in 4k, and I'm looking for the great overall preformance. I will also be dual booting the computer to run Windows for gaming (on a 4k Monitor). My budget is around $700 for the GPU. I'm fairly new to the Hackintosh world, so let me know what you think.

Thanks!

NOTE- The Specs listed under my profile are not for my new build. That my old PC, which I plan to sell.

Have you read any about the Vega builds? That would be a great direction to look because it will soon be the best native gpu for Mac.
