I would point out to him from your motherboard manual:
22 AGP PRO slot. This Accelerated Graphics Port (AGP) PRO slot supports 1.5V AGP4X mode graphics cards for 3D graphical applications.

As I mentioned the card you have is 8X. Many cards are 8X/4X or backwards compatible but they usually say so. That 5500 does not say so. You might want to mention this.
