ATI has been making FireGL cards for a long time
ATI has owned FireGL for only 5 months. They haven't made any FireGL cards, but are just contuniuing to manufacture them. And, they don't intend to carry on with the line. They plan to release Workstation class cards based on the R200 and later the R300.
So, [wusy,] it would seem that ATI is also setting out to rip off the professional people's "monay".
High fill rate is not of a major concern, since getting X frames per second isn't the developers worry, instead you need brute power. That is why cards like the Wildcat have multiple chips setups, and are the graphics developers choice. Full featured final renders are done mostly by the CPU. Besides, The nVidia cards seem to be better at textured operations anyway.
Having said all of that, since both Quadro2 and FireGL2 cards are similarly priced, the FireGL would come recomended if you want to do anything more than the casual 3D work. If you want to play a game or to and do some 3D work as well, I think Just get a GeForce 2 and then do yourself some soldering.
