So. performance per mm^2 win for ATI (not surprizing, they have 45nm process vs NVIDIA 55nm). This translates to cheaper chips for the same performance.
But performance per W I think is in favor of NVIDIA. Definetely at idle speeds and even in 3D (260 is slightly faster than 4850, and g280 is much faster) That translates to higher electrical bills especially when they multiplied by the fact that you need air condition the room better.
It would be interesting to calculate price of ownership which includes the price of electricity over 2 years, because it probably can be about couple hundred dollar difference between those two (depending on the use) just due to electricity consumption.
