For those of us that don't have the resources to upgrade our systems in one go, say from a AGP to PCI-e based mainboard, MSI have come up with a solution that allows the card to be used in either AGP or a PCI-e slot.
Visitors of MSI's booth at Computex 2005 had the chance to see the first graphics card that supports both AGP 8X and the PCI Express x16 interfaces. The card can be installed either in an AGP or a PCI Express slot by simply mounting it on your main board in the corresponding direction: the topt edge of the card fits in PCI Express slot, while the bottom edge fits in the AGP slot.
MSI showcased the RADEON X800 XL with the PCI Express interface embeded in the video chip while the AGP interface uses a bridge chip. Information about when the card will be launched on the market is not yet available.
