A simple question guys and gals. I have an infinity for dell dimension 8100 and optiplex gx 400 towers. The boards are similar, vintage from the late 90's. They both use APG NVIDIA brand video cards, typicaly VGA only, although I have seen Svideo, and DVI, and even ANALOG line out connectors. How do I identify the model number of a given card to determine whether it would work in these boards. The NVIDIA part # eludes me. There are any printed #s on the card, both on labels, and in white ink. I do not see any I recognize as in ATI, GE FORCE, ect. I have several APG video cards in my pile and I need to identify them. Swapping cards is a slow way to test. In addition this process produces eveything from NO video to incorrect colors, to noise bars. Any info welcome. A list of compatible cards from N or others would also be welcome.
