Start-menu-->Run-->dxdiag and hit enter. Switch to the 3rd tab (i don't know wtf it's called), you should however see the test direct3d and directdraw. Your gfx card is listed there.
If you are using Jabo's plugin: It should be listed in the Video plugin section, icon three, as said, or if you are using the Daedalus Plugin, it will appear just before any game starts at the bottom of the window.
