Which video driver (card) is better?

I just got a new hp pentium d 3GHZ system, on board is a Intel 950 accelerator 82945G express chipset driving the video. I have in my old computer a Nvidia Geforce4 MX4000 3D Fuzion graphics card. Should I install the Geforce card or run with whats on board? Which will play games better?|||The onboard is better, but there are several games that won't run on it at all, and some others that will render incorrectly or very slowly. For a good gaming experience, you'll have to get a modern discrete graphics card.|||cant answer unless we know what you have on there, unless its the cheezy internal motherboard video if its the mobo doing the video get that g4ce in there right now.|||the onboard is optimized for the system it will work better than the card Intel favors ati cards the pent4 and intel chip sets they use hyper threading whereas the nvidia sides with the amd and hyper transport
