ok, lets NOT get into a 3dfx sucks argument, whether it's becuase they use twice the RAM/Chips, etc.
now, I have to say this. Benskywalker, I'm sure that they DO have the ability to understand the double, and now Quad pumping (for the V5) of the AGP port. they don't necessarily understand anything else. BTW, I have my AGP port (which has a V3 in it) on 2x, how do I know whether it's actually running 2x, even though the BIOS says it is?
