My old computer had a built in SIS 530, and it really sucked. It was an integrated AGP 8meg 2d/3d adapter, and 4 of those megs were shared, so it took off 4 megs of the system memory! The 2d was ok, but the 3d was horrible, it could not even run Half-life good! I probably did not answer your question, but from what I understand SIS is pretty low end in graphics.
