"AMD Eyefinity and Surround mutli-display setups are continuing to grow ever more popular, however with most GPU's you can't just connect any three monitors onto a card and expect Eyefinity to work. Some level of planning is required, and in most cases at least one DisplayPort connectoion must be used. Sapphire's answer to this inconvenience is the FleX line of graphics cards. Lke most cards, these are equipped with two DVI connectors. However, a third DVI monitor is also supported thanks to the Sapphire HD 7870 FleX's HDMI to DVI adapter. This makes things just a little more "FleXible" for users planning an Eyefinity setup!"
