There are many video cards. Most are specialize for 3D playback (consider game card)and high performance for 2D. The two that I know off (yes there is others for serious application)is from Matrox and 3D labs but you have to know which card to choose. Most 3D artist are looking for "Rendering Card" but it's yet to be seen on the market. Do vist their web site for more indication of what you need.
