Review: HD 6770's cheaper evil twin
Radeon HD 5770 Flex Edition is a graphics card for multi-display solutions. Namely, the card allows for connecting three displays without using DisplayPort or active adapter, or four displays if one o them supports DisplayPort.
AMD recently renamed the HD 5700 series to HD 6700. As usual, there were no significant changes other than the name, although the “new” series did get HDMI 1.4a and Blu-ray 3D support.
Apart from the HD 5770 Flex Edition, Sapphire also offers HD 6770 Flex Edition, although there’s almost no difference between them.
If you’re looking for an affordable card that will allow for four displays at the same time, then you’ll definitely like Sapphire’s HD 5770/6770 Flex Edition. However, four-display gaming is not quite a walk in the park and you you’ll need a faster card for that purpose.
HD 5770 Flex Edition is available for less than €100, whereas HD 6770 Flex Edition will cost you about €108, here and here.
