Ok, but I'm not very good at writing guides, so hopefully you can follow along. You will only need this until 10.8.3 comes out, the drivers should be included then. First, you will need the 2 programs i attached and the NVidia Drivers, found here:
http://www.nvidia.com/object/macosx-304.00.05f02-driver.html
Install the 2 programs.
Right click on the NVidia Drivers .dmg, open with Pacifist
In Pacifist, click on "Contents of webDriverPayload_jLhsf.pkg" then click "Extract to" I put mine in a folder called NVidia on my desktop.
Run "ShowAllFiles" click Show.
Open the Unibeast USB in finder. You should see more files and folders now.
Open the folder System, then Library, then Extensions. You will need to delete the NVidia drivers in this folder, delete the following: NVDAGF100Hal.kext, NVDAGK100Hal.kext, NVDANV50Hal.kext, NVDAResman.kext
Open your folder with the new NVidia .kexts in it, copy them to the S/L/E folder. Now make sure you can see the Extensions folder, it will make the next step easier.
Open Terminal, type "sudo-s" enter
enter your password
type "sudo chmod -R 755" press the space bar once, to leave a space after 755, now, drag the "Extensions folder" onto Terminal, it should type the path for you. press enter.
type "sudo chown -R root:wheel" press the space bar once, to leave a space after wheel, now, drag the "Extensions folder" onto Terminal, it should type the path for you. press enter.
type "sudo touch" press the space bar once, to leave a space after touch, now, drag the "Extensions folder" onto Terminal, it should type the path for you. press enter.
type "exit"
type "exit"
close terminal
Open "ShowAllFiles" click Hide.
Now boot with your Unibeast install with the New NVidia drivers. Remember to boot with "GraphicsEnabler=No" and to install the NVidia drivers after you run Multibeast. Just use the NVidia installer. Reboot your computer, and you should be good to go!!!
