What is the process to swap from an AMD to NVIDIA video card

[mikerogers56]

I currently have an XFX Radeon 5770 and have ordered a PNY GTX660 Ti. What do I need to do to swap these cards and not break anything doing so?

Thanks

GraphicsEnabler=No

I'm in the exact same boat... (except I have a flashed 6770>5770)

I presume you've not applied any other patches, or installed anything else to enable your graphics card as it is already supported in vanilla OSX.
The GTX 660 Ti is also supported in vanilla OSX, so you'll be able to swap it out no problem.

the short answer:
You shouldn't need to modify anything, but 'GraphicsEnabler=No' upon boot.
