<P><FONT SIZE=2>My experience has been that the graphics card and RAM make the biggest difference, but I'm not doing volume rendering. The nVidia GForce 2 & 3 (soon 4) GTS or Ti based graphics cards are quite impressive when it comes to OpenGL performance. ATI's OpenGL implementation has traditionally been poor, but since they bought the FireGL line, that may change.</FONT></P>
