When KitGuru reviewed Sapphire’s HD5770 Flex Edition last year, it walked away with our top award. It was not only an amazing productivity board, but in a CrossfireX configuration it was capable of reasonable frame rates across three screens. Today we are looking at the new Sapphire HD6870 Flex Edition, a more powerful update in the FleX series. We will not only be testing this across three screens, but across four screens at 7680×1080 resolution in a CrossfireX configuration.
