No need to worry about a question looking stupid - it is the best way to
get an answer!  ;-)

The ATI is a combination 2D/3D accelerator while the Voodoo2 is 3D only.
The 2D acceleration helps your CPU with rendering your desktop and
applications like your browser and video playback etc, while 3D
acceleration takes a lot of the burden off the CPU in rendering 3D images
like in some game environments and CAD packages etc.

The ATI does a reasonably good job on the 2D but not so good by today's
standards on the 3D.  The Voodoo2 is still a good 3D card.  It is designed
to work in concert with AGP cards like the ATI.  The output of the ATI
"passes through" the Voodoo2 on the way to the monitor.  When you are
running an application that requires 3D rendering, the Voodoo2 "takes over"
and switches off the pass through channel.
