I thought we would've all learned by now that it's not how much bandwidth or how many meagherts you have, but how efficiently you use them. I mean look at SLI, granted it's still brand new, but I mean when a single 6800GT beats out dual 6800 Ultras, proves the point pretty well that you can have all the power in the world, but if you can't make good use of it, it's worthless. I think AGP costs more because they're selling chips that are native PCIe and they have to manufacture and implement a small bridge chip into the board circutry which further cimplicates the process and of course the added cost of the bridge chip itself.
