A 280GTX throttles itself down to 300Mhz and the ram down to 200Mhz when idle and drops the voltage, that is why the idle power consumption of the 280GTX is so much lower than the 4870 idle. This is also why it generates less heat than a 4870 when idle.
Under load the 280GTX easily generates as much heat as the 4870. The problem with the 4870 is that it is constantly generating a ton of heat even when just sitting on the desktop. ATi needs to get PowerPlay working.
Yes but what about when you're in Vista and with Aero ON?
I was thinking of adding this to my system if I get 4870 --- http://www.thermaltakeusa.com/produc...2414/A2414.asp
