The confusingly-named Nvidia GeForce4 MX 4000 (a PixelView in this case)
The only model in the GeForce4 line-up that mixes the 4-digit scheme used by real (Kelvin architecture) GPUs with the "MX" term used by "improved Celsius" GPUs.
For those unfamiliar with Nvidia's underhanded marketing tactics: of course it's an "improved Celsius" with no DX8.0 support.
