Typical of most GeForce cards, the BFG GeForce 6800 GT OC is a bit longer than ATi's counterparts, which may or may not cause a little concern if you're thinking of installing it into a SFF (small form factor) system. On the bright side, however, unlike the GeForce FX 5950 Ultra or 6800 Ultra, the 6800 GT models are shipping with a one piece heatsink/fan that covers almost the entire front of the card, cooling the GPU and RAM, and requiring only one slot. The back side of the card is mostly bare - all of the RAM chips are on the front, and only a small plate rests over the back where the GPU is situated.
A quick look towards the end of the card shows all the differences we could find between a 12-Pipe GeForce 6800 and the BFG 6800 GT OC. While we can count at least seven large capacitors on the reference 6800 card, the BFG 6800 GT OC has just two. However, the BFG model has a strip of MOSFETS underneath a thin heatsink (the black strip along the edge in the leftmost picture). The main heatsink to remains the same. It's a large aluminum block broken up by a heatpipe that curves up away from the center and then down along the right side. This helps pull the heat away quickly from the midsection (over the GPU).
Finally, we saw the usual VGA, DVI, and S-Video outputs, which includes all of the kinds of connections your likely to make. Should dual VGA monitors be in your future, the DVI-to-VGA adapter can be placed on the DVI port to allow for two 15-pin VGA ports. Also, like the GeForce 6800, only one 4-pin MOLEX connection was required to power the card. To allay any fears about power consumption or otherwise, BFG states that a 300W Power Supply Unit will suffice for powering the 6800 GT OC.
