As described in the article Linux has some problems with the high end NVIDIA cards. Better to say NVIDIA has some problems with Linux. The NVIDIA drivers simply are not well maintained and are not open source. After I bought a high end Lenovo 520 with NVIDIA quadro 2000 I had to revert to Windows 7, waiting for NVIDIA to finally provide the right drivers or make things open source.
I maintain quite some computers, all under Linux Mint. All users, from schoolgirls to their parents and teachers are happy to finally have computers that simply work, do everything they need and everything they want. I am sure that Mint 12 will be again be a leap forward to make it even better than the previous versions.
