 ATI's CrossFire connector (CrossFire Bridge Interconnect, or CFBI link) is now a ribbon-like connector attached to the top of each graphics adapter, similar to nVidia's SLI bridges, but different in physical and logical natures.As such, Master Cards no longer exist, and are not required for maximum performance.Two dongles can be used per card; these were put to full use with the release of CrossFireX.
