Trying to find out what the most powerful, (ahem), AGP GPU would be for my Dell Dimension 4100. Has a whopping 512mb of.... hold onto your hats.... PC 133 ram! Anyway I really enjoy working with older tech, and could not find an answer anywhere else so should have just started here to begin with. Currently has an MX 400 64mb card......yeah, I know.....but it's just plain good stuff!!! Thanks!!!!
