ATI's (not yet DAAMIT then) answer at Computex was clear: 2 x PCI-E 16 lanes in those two graphics slots, plus one PCI-E x 4 slot (x 16 connector) for the physics accelerator - that was when ATI started pushing the idea of on-GPU physics chippery and demoed the X1900 chips doing it all over the place. All seems to have gone quiet since then on that front. Anyhow, that was on top of extreme overclocking possibilities, plenty of interfaces, fast memory controller and few more PCI-E lanes for other peripherals, and so on.
Then DAAMIT came to be, and so did many other things, including uncertainty over the fate of this chipset, coupled with substantial success and performance-crown-snaffling by the Nforce 680i. After all, Intel has not too much interest in its chief competitor influencing its systems, nor did AMD have much interest in creating a 'too good' chipset for its, well, chief competitor..
