KitGuru has reviewed many AMD HD6870 graphics cards in 2011, but today we are looking at something very special, the Powercolor HD 6870 Eyefinity 6 Edition graphics card. This particular board is supplied with a custom heatpipe cooler, 6 mini DisplayPorts and an additional 1GB of memory to ensure that performance is strong at very high, multi screen resolutions. This card is based around a Barts XT GPU with 1120 stream processors. The core is clocked to 900mhz and the 2GB of GDDR5 memory is paired up with a 256 bit memory interface which runs at an effective 4200mhz.
