It must be time for Toms to do an aftermarket cooler shootout on 8800 cards. My prediction would be the Thermalright HR-03 will reign supreme in the air cooling segment, with the DuOrb a surprisingly (since it weighs less than the stock cooler) close second.
I'm not sure the DuOrd is available anywhere yet, its on 'pre-order' at most sites that list it.
