DBC works pretty well for me with the Intel Graphics card although I have to admit that I'd like to upgrade it very soon. I just upgraded my main memory with another 512MB.
If it is for your enjoyment, then get the best you can afford. If you are making something for others, then the average computer will probably have some kind of integrated card and many users are afraid to open their computers up to install another card. They expect to put a CD in and magically it will run the game, full speed, great graphics, and so-on.
And with that I have a question that I need to post to the board now for myself.
