Caarrie is exaggerating about intels inability to run ps. My gm915 chip was able to run ps, with some graphic glitches (some black hills and flashing portals) and sometimes low framerate. If you are not able to run it with a newer chip, it will not be because intel in general does not work well with opengl as Caarrie states.
Newest driver and fiddling around with graphics settings should at least get you a version the shows most of the graphics.
