I recently had my computer upgraded with a new motherboard (MainBoard TX Pro-II) and CPU (AMD K6-2 with 3DNow!). The motherboard's owner manual says that it features a 66MHz Advanced Graphic Port, however, upon close inspection of the motherboard I found out it has no AGP slot. I currently have a Matrox Mystique 220 PCI graphics card and was looking forward to upgrading to an AGP card. What do they mean with AGP support if it has no AGP slot? Also, if I can't upgrade to an AGP card what is the best PCI 3D card considering both price and performance?
