The Inq reports ATI is working on some kind of uber watercooled edition of the Radeon X2800 (R600).
R600 Uber edition will end up as the fastest R600-based card of the first batch on the shelves. The key secret is a water cooler. We heard that two companies are competing to make the cooler. One is Aavid , which we have already seen on many graphic cards and the second is Denmark-based Asetek.
We hear that the water cooler has both water pump and the reservoir on the radiator. So the card will look similar to the other cards, just with bigger radiator, powered with fan, and a reservoir.
You should not end up with lot of wires and tubes from and to your card. It should be the fastest card around but we will have to hold our breath for a while more yet.
