It is hot. And brilliant for other uses. TDP is way too high for air cooling, though. Fortunately, gamers are not Luddites and will use liquid cooling when required.I think review sites should use that as the new test for heat. If it ruins the drink before it's finished, the card is reviewed unfavorably.
Seriously though, I just don't see the need for video cards to eat up the energy like that! Just thinking about 800 WATTS of power being used by one component, makes me hot.
