February 23rd, 2006 -- Quadro FX 4500 supports CGfx in Maya 7, but only if you enable it. I found this on the Maya 7 support site:
NOTE: The Quadro FX 4500 has been tested and qualified with CG enabled in Maya 7.0. The use of CG is not on by default and must be turned on using environment variables added to the Maya.env file. This file exists in your HOME/Library/Preferences/Alias/maya/7.0 directory. The environment variables are as follows:
When we defined those variables, our Quad-Core with FX 4500 not only completed "production quality" HW renders as much as 216% faster, but the final product looked better.
And there's more! We discovered that the GeForce 7800 GT supports CGfx, too, though not "qualified" by Alias/AutoDesk. We "qualified" it and can assure you it does HW renders just as fast as the Quadro!
