Matrox Millennium G400 MAX
With this dual-head card the Matrox' G400 offers excellent 2D quality for two monitors.
The G400 is basically a G200 but fixed and tweaked. New features like Environment Mapped Bump Mapping (See Wiki) have been added.
Specifications-wise the G400 has pretty much but in the year 2000 the driver support wasn't so good. Let alone OpenGL support.
