Just tell your motherboard.
Also,6800gt pci-e shod be starting at abt 24k.
THough x800xl you shd get around 20k.
Also,if somebody has 1.7ghz , he shd upgrade if not now then within few months as that is a bottlenekc also now since pci-e is out it is safer to stick with wit or atleast 8x.
THough ask others abt 4x.
just upgrade 1.7ghz
