Open up the computer (you will have to do this to put in a new card, anyway).
Look at the slot that the video card is plugged into. If it is different than
the 3,4 or 5 next to it, it is an AGP (there is only one AGP, but usually more
PCI slots). The AGP slot is also spaced further away from the back panel of
the computer, and is brown, and the PCI ones are black or white.
If you currently have a PCI card, but there is an AGP slot available, you
could change to an AGP card, or vice-versa. Most newer cards are AGP, except
some very new ones, which now are PCI-E (which you don't have in a Pentium 3).
