I have had ONLY NVidia cards since my first ever own PC in 2000 when I started college.
I've used Mandrake Linux for a while then switched to Ubuntu when it came out in 2004 and have used that ever since.
I've NEVER encountered any problems whatsoever. In fact, it made using an NVidia card easier because of its built-in third party driver installation tool that takes care of everything.
If something doesn't work, it's very probable that it's because the user messed around with something and caused it to happen.
