Can i replace the video card in my D600, and if so then with which one?

I need a new video card for my Latitude D600, Is it possible to replace it? and if i can, i need one with 128MB and it needs to support Pixel Shader 2.0|||It's a laptop.

You can't upgrade the video card because it's embedded i.e.wave soldered to the motherboard.

And there is no slot for a card.
