CustoMac Pro + Gigabyte GTX 980Ti 6gb windforce

Hello,
I'm building a CustoMac Pro based on the buyers guide, the only difference is the Gigabyte GTX980Ti 6gb windforce as a graphic card.
Do you have any advice for this setup or something to keep in mind about this video card?

I will be using it for video editing on the hackintosh side and maybe a little gaming on a windows boot.

this is the list of components

Processor : Intel Core i5-6600K 3.5GHz Quad-Core Processor
Cooler : Corsair H60 54.0 CFM Liquid CPU Cooler
