Hackintosh GTX 570?

Hey guys - I just built my first computer/hackintosh. Here is my build -

Gigabyte Z68X-UD3H-B3 Motherboard
Intel Core i5 2500k Processor
Corsair Vengeance 16gb RAM
Nvidia GeForce GTX 570 Graphics Card
OCZ 600W Power Supply
Western Digital 1tb Caviar Black HDD (x2)

I have windows installed, and am ready to install OSX Lion onto my second 1tb hard drive. My question is - will the GTX 570 work 100%? What will I need to do to get it working? I am a total newbie to this - does Multibeast enable graphics? Do I have to download .kext files? Just wondering if the GTX 570 will work, and how to get it to work.

Thank you very much.
