3DLabs Wildcat II 5110
3DLabs Wildcat II 5000
ATi FireGL 2
Elsa Gloria III (Nvidia Quadro II)
Geforce 2 GTS
Geforce 3
To make it even more interesting, we've also included the Gloria II (Nvidia Quadro). This way, you should be able to estimate how much performance an upgrade to a more traditional professional high-end 3D accelerator (i.e. Wildcat, Gloria III, or FireGL) will buy you.
