I'm currently seeking a card for an older box. This box has an ASRock p4i45GV motherboard equipped with a 2.4ghz intel processor so I'm not sure if this applies to you, or not, but here is the one that I'm thinking of:
3D Fuzion 3DFR66256 GeForce 6600 256MB 128-bit DDR AGP 4X/8X Video Card - Retail
Here is a thread that I started on the "Tomshardware" site that gave me some clue of what should be looking for.
Graphics card: PCI or AGP for an older computer with a p4i45GV MOBO`
I hope that is some what helpful.
