RampageDev's guide's references to Clover are obsolete, the config.plist file, and clover-injection stuff has changed from the version in the guides. Also, the direct DSDT/SSDT section needs to be updated, as "DSDT Editor" has been replaced with MaciASL, and the details of it's use are different. But most imprtantly the DSDT content for NVIDIA is so different that the instructions for finding the device code, and pasting in code, do not work. Re: running on one card, both 8800s are old (2006) in a liquid-cooled loop. If I were to remove one card, I may as well replace both with a modern card. That = $$$
