If the Socket T board is based off the Intel chipset, then there is a good chance that is will not have an AGP slot and just a 16x PCI Exress slot. Some mainboard manufactures have found a work around, but I don't think all of them will do this. Just make sure you check out the board before hand. I believe VIA and SIS are making socket T chipsets that support an AGP slot and a PCI Express 16x slot.
