ATI's x1300 and x1600 series cards do not currently require a master card to run in crossfire, due to the fact that there is enough bandwith on the PCI-e bus to pass the information between the 2 cards. Now, ATI's upcoming chipset will double the number of lanes available to each card. Will this allow for example 2 x1800xl to run in crossfire without a master card? Or am I being optimistic?
