|The GF4 MX 440 is based on the GF2 & only supports DX7. You may have DX9 (or DX8.1) installed, but your card can't make use of it.|
"So the new rev of the MX 440 should be a little faster than the last one, especially when it comes to running apps fluidly at higher resolutions. Beyond that, it's still a DirectX 7-era graphics chip, with none of the new abilities of DX8 or DX9-class chips, like vertex shaders or floating-point color datatypes."
