As for video cards being obsolete... well that REALLY depends on what you do/need of them. If you like playing video games (i.e. have no life), then you may not be satisfied with a GPU of a decade ago. On the other hand, if you are more interested in productivity, engineering, or servers -- you know, much more PRODUCTIVE uses for computation, then the power of the GPU becomes FAR FAR less relevant.
MUCH more important than balls-to-the-wall performance out of a proprietary blob driver is OUT OF THE BOX SUPPORT. This is something that nvidia TOTALLY LACKS. AMD, unless you are looking at the newest and fastest GPUs they produce, has virtually perfect out of the box support and the SAME kind of support for the newest and fastest as nvidia via their blob driver.
Now one of the MAJOR problems I have with nvidia is with their blob driver's reliability and compatibility. They do NOT support Linux in the way that is most compatible with the system. Even POULSBO is better since they have at least implemented things like KMS. Nvidia? Just keep doin' it the OLD way..... and occasionally break totally so that your users can't do normal things like switching VTs.
So no thanks. I'm finished suffering with nvidia.
