After careful consideration I have decided to transfer all hardware review activities to a new domain.  I purchased in 2012 and have been working hard to build a new and improved Ninjalane on that domain.  If you are reading this you have reached one of the archived articles, news, projects and/or reviews that were left behind during the site migration. 

Please update your bookmarks and be sure to visit the new and improved Ninjalane at

    Card Layout and Features

    The Sapphire Radeon HD 5770 Flex is a nice looking card with a unique and heatpipe enabled heatsink.  Aside from the heatsink the rest of the card is similar to most of the other reference Radeon HD 5770  cards on the market today.
    Sapphire has chosen to use a blue colored PCB for the Radeon HD 5770 Flex. Graphic memory is made up of 8 total memory chips, 4 on the back of the PCB and 4 on the front.  The card supports a total of 1GB of GDDR5 memory.
    Two Crossfire bridge fingers found on the Sapphire Radeon HD 5770 allows it to be linked with up to four cards in a single system. Crossfire power like this can easily beat a Radeon HD 5870 in any graphics test.
    The Sapphire Radeon HD 5770 Flex is 16x PCI-Express 2.1 compliant card but is able to work in any older version of the 16x PCI-Express slot.
    Radeon 5770 Flex looks very similar to the old reference boards when looking at the digital output area. In a way it is, but with a slight little twist. The 2 x DVI, HDMI, and a DiplayPort connectors can all be used at the same time to power up to four monitors.

    Things to know: The HDMI can be converted to DVI, and the black DVI will not support a Dual Link DVI.
    Power consumption on the Radeon HD 5770 is extremely good and only requires a single 6-pin PCI Express connector to run.  Available system power should be in excess of 475 Watts.
