professional hackintosh amd card need help

Hello

I require a machine for massive video productions (Afterefffects, Cinema4D and more on the 3d rendering part).
As you well know, Macs pro are crazy expensive and the parts, well..
I need to run MadMapper and all sorts of MAC related software, but also need a AMD Card and i need your help here regarding compatibility.
Reading your tutorials, i have come to the conclusion that the below list will works, but the problem is that the card that i need is an AMD FirePro W7000, because of the ability to use 4 displays and also the price point. Quadros are way over-expensive at this point.

corei7 3930k
h100i
asus extreme mb or related gygabyte high end one.
rackmount based case
raid card
ssd raid 1+0 or pci based if possible if faster.
tons of ram (32gb)

Any help will be really appreciated,

Thanks,
Diogo Ferreira

You might wait and see what the cards shipped with the new MacPro turn out to be. The PC versions of the new AMD firepro cards might get better support in future versions of OSX.

this cards works OOB natively on OS X 10.9:

GIGABYTE Radeon R9 280X (GV-R928XOC-3GD)
GIGABYTE Radeon R9 270X (GV-R927XOC-2GD)

I have a GA-B75M-D3H Mainboard and a GIGABYTE GV-R927XOC-2GD Gfx-Board.
The 270X is very slow on OS X 10.9.2.
How can I get it to full speed?

I have the gigabyte r9 280x the some one in the post but the problem is i cant boot unless if i boot with the IGFX First!
