the guy has AGP, thats 1 slot, that does NOT work with pci-e cards
i order to use SLi you need the fallowing:
1-a mobo w/ 2 pci-e slots
2-that mobo has to support SLi
3-2 vid cards that are pci-e and support the SLi funtion
the 6800 ultra comes in 3 flavors:
agp (this is the only one he can use!)
pci-e
pci-e w/ SLi support
he can only use agp, so forget about buying a card later for your current rig. so go buy buy a good agp card. or wait it out and buy a new rig with a SLi graphics system :Oo:
