Things are changing fast. Nvidia has their own "open source drivers" that are almost identical to the proprietary ones and the NVK project has open source drivers that might outperform the proprietary drivers in most games.
Now the only reason you might install the property drivers by the end of this year is cuda and potentially open CL.I think they're protective of their drivers because about the only thing separating their rt cards from their quatro cards are their drivers and software locked features. Quartos probably get put in more Linux systems than any other type of system.
