9800GT will work on the ASUS P5KPL-AM because PCI-E 2.0 is backward compatible with PCI-E 1.0.
But it wont work on the Foxconn model since the foxconn model has APG slot and 9800GT is a PCI-E card.
Nope the Foxconn has a PCIE slot and in fact am using a 8400GS PCIE card in it. Just the 9800GT doesn't work yet I had it tested by the dealers and it works. Will try it in the Asus board but am told the 9800GT needs a PCIE2 card becuase it requires power directly from MB since the 9800GT I have does not have any additional separate pwoer connectors.
