Ah yes I must have missed that part about it being new. Disregard what I said then. The only difference between the single pipe and double pipe is the heatsink. The double pipe, obviously, has 2 heat pipes on it. The first heat pipe, leads to the GPU fan on the right side of the system, while the second pipe leads to the other side of the system and the fins sit behind the CPU heatsink, next to the CPU fan. It just provides more surface area to give better cooling. The rev. 1 cards don't have a change to the cooling system, they changed the bios set up (probably to stop people from flashing the 7900 GTX bios to the card).
