well i decided to get a old used pc and upgrade it, my old pc has a ok graphic card which i want to use for my dell its a radeon 3650 AKA AH3650 i want to know will it work properly on the dell
It will not. The Dimension 2400 doesn't have an AGP slot required for that 3650. If your old PC has an AGP slot chances are it is probably better than this Dell. If we had some more specs we could probably lead you in a better direction.
