Your assessment of the GF3 isn't quite correct. Yes, you will pay a premium
for it. And it is true that most of the new features (per pixel shading for
example) aren't utilized by most current software packages. But the GF3
sports a new memory architecture and faster clock rate which helps to push
more data making it faster than any consumer level graphics adapter on the
market even for such mundane tasks as data visualization.

Yes, there are professional cards that will outperform the Geforce family.
It is too early to say that professional cards in the sub $800US range
outperform the GF3. I haven't been able to find any benchmarks pitting the
GF3 against professional cards like Diamond's (sonic blue) FireGL or 3d labs
Oxygen GVX1 so I think the "hands down" comment is a little premature. I do
believe that a price/performance comparison favors the Geforce cards but
this is more of a gut feeling.
Take a look at this comparison of the FireGL vs GF2 GTS vs Quadro2 Pro:
And a slightly more dated review of some more professional 3d cards:
I think this discussion is in some serious need of real numbers. It is clear
after parusing the two articles above that there are HUGE differences in
performance between applications and that this discussion can only be
answered with some IDL specific benchmarks. Hopefully this thread will
ignite some interest in John-David Smith's posting regarding an object
graphics test for IDLSpecIII.
They are useless for games but superb for CAD.
