Here is the solution, which you can use to enable most newer Nvidia GFX Cards if they don't work out of the box.
Use Post Installation toolkit to choose a proper Nvidia Enabler option to apply to your new Mavericks Installation.
Pandora's Post Install Toolset
First off, thank Pandora Team for making this happen. They're awesome for spearheading development on this one-shot tool to create a good Mavericks installation in minutes and the devs of all the bits and pieces in post installation. We salute you. Without them, OSX86 wouldn't be where it is today.
I Hope this helped serve as future reference for those looking for answers. Happy "hackintosh-ing"
