[vtkusers] What's the most important : CPU or graphic card

[Jerome, Ron]

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.
