I am not an expert, but doesn't AGP 8x still support AGP4x cards? Isn't at least the Voodoo3 and up, Radeon 7000 and up (among others) AGP 2x/4x cards? Shouldn't these work on an AGP8x motherboard?
AGP 1.0 covers 1x and 2x
AGP 2.0 covers 4x
AGP 3.0 Covers 8x
I don't think AGP 3.0 has any support for 4x.. but Downix will probably prove me wrong again today :-)
