GeForce FX 5200 is a DX9 video card while MX440 is only a DX8 card. 5200 can at least run modern games such as Far Cry and Doom 3. The MX440 is completely outdated, does not support DX9 games or Pixel Shader 2.0. It will have trouble even running Quake III engine games. Although I wouldn't reccommend either of these cards, I would much rather the FX 5200 than the MX 440.
