Alright,

I have done my research, I have tried and failed and now I come to you for help.

Since my post on insanelymac.com was rejected I'll try to keep it clean and simple. Starting with my hardware specs.

Code:
Motherboard: ASUS M4A89GTD PRO/USB3
CPU: AMD Phenom II X6 1055T
RAM: Corsair Vengeance DDR3 1600MHz 8GB CL9
Graphics card: Sapphire Radeon HD 6870 1GB GDDR5 (x2 in cross-fire)
Now my questions are as follows;

Can I successfully deploy Mac OS X on my computer?
Is it possible to take advantage of both my graphics card?

Thank you in advance!
