Replacing the video card is only an option on a small number of laptops, and I dont think that the Sager NP3790 is one of them.
nVidia cards that use the 71.XX drivers wont work with the proprietary drivers on newer linux versions. 96.XX might be losing support soon as well.
BTW, generally, the ATI drivers havent been the best in the past. ATI/AMD is changing, the newer proprietary drivers seem to be getting a lot better from all the reports I've seen. As far as open sources drivers go, they have developers working on the open source drivers, and have opened at least some of the needed technical specifications needed for other 3rd party developers to make better drivers. nVidia isnt doing that, they wont help nouveau at all.....Then there is the whole nVidia optimus problem, lots of people have been caught out badly by that.
IMO if ATI/AMD and nVidia keep going like this, 'nVidia is best for linux' will be a thing of the past.

True, but I know I've seen a lot of ubuntu users having problems with the open-source ATI/AMD drivers.
You could try the xorg-edgers PPA to get the newest drivers, it seems to help some people at least.
Add this to your software sources-
Then update, that should get you the newest free radeon driver.
Gallium3D is worthing looking at as well.
