AGP Compatibility: The Short Version
If an AGP card fits in an AGP expansion slot then they are compatible. But read the rest of this anyway. There are some rare exceptions where motherboard and video card manufacturers don't obey the rules.
AGP Compatibility: The Long Version
AGP Basics
In 1996, Intel introduced AGP 1.0. AGP was a modified version of PCI designed to speed up transfers to video cards. It was followed by AGP 2.0 in 1998 and AGP 3.0 in 2002. Each new version added new speeds and signaling voltages.
