"The SAPPHIRE Flex HD 7770 GHz Edition is the latest entry into the Sapphire’s Flex line up, bringing the ability to run multiple monitors without the need for an expensive cable or adapter. AMD Eyefinity is one of AMD cards’ unique features, and it allows for up to six displays. For professionals like graphical artists and video production companies that need multiple displays, this is a great way to increase productivity without the need for multiple-GPU. Unfortunately, in order to power these displays you would need a monitor that supports DisplayPort 1.2 which supports Multi-Stream Transport (MST) to daisy-chain the displays. Alternatively, you can also buy a a DisplayPort 1.2 Hub MST for the multiple displays.
While DisplayPort is gaining popularity, monitors with such ports often cost more than those without. Since we do not swap monitors as often as other computer parts, and many older models lack DisplayPort, it would be difficult to run your multiple monitor setup if you have one of the latest Radeon GPU’s. This is where the Sapphire Flex card stands out among the other Radeon graphics cards."
