The Sapphire card is a dual slot video card meaning that you will have to have an extra free slot on the motherboard besides the graphics card slot to install the card. The card has a heatsink covering over 66% of the card with an 11-fin fan in the center of the heatsink covering the graphics chip. To the right of that heatsink is another heatsink covering the memory chips.

The heat plate is on the rear of the heatsink and operates like a heatpipe in many ways. The heatpipe transfers the liquid inside it to the outer portion of the heat plate where it condenses into vapor then cools down to liquid which starts the process all over again. In operation the card reached 56C when idle and 68C when under stress.

The rear of the card has the part number and serial number stickers. As the card has 2GB of memory, the memory is on both sides of the card. A heatsink covers the memory on the rear of the PCB. Four mounting nuts for the graphics chips lie under the heatsink. The back of the card has two 6-pin power connectors to provide power to the card as it requires more power than the 75W of power the PCI Express slot can provide. The rear I/O on the card consists of three connectors: a HDMI port to connect to an HDMI monitor or HDTV, a Dual-Link DVI port and a VGA port. Note you can use more than one DVI-I monitor or HDMI monitor if you use converters.
