The fact is that NVDA has the market saturated with a full line of high quality cards that consistenly outperform the competitors in the Same price range. If you want the best performing most expensive card out there you'll have to get a GForce2 Ultra 64. If you only need a decent sub $100 card with tv out and on board DVD decompression for your moms computer you'd be silly to get anything other then the gforce2 MX. And then there are the cool features that I personally know a lot of folks taking advantage of such as dual display.
Plus there is the GForce 3 which is unlike anything anyone has ever seen. I work for a video game company and us programmers are slobbering to get our hands on this machinery, as I expect all of the other developers out there are. The next generation of games is going to be taking full advantage of pixel/vertex shaders. http://www4.tomshardware.com/graphic/01q1/010227/index.html
