Another anti-nVidia piece by TheINQ, whats new... :p
I call BS on this. Heat doesn't seem to be much of an issue for the 450W 4870X2:

So with the touted theoretical 20% lower power draw from 55nm, we get ~250W for a single GTX280. Since an 'X2' card doesn't double power consumption (4870 = 280W, 4870X2 = 450W so ~1.6x gain in power consumption) a 280GX2 could conceivably run COOLER than the 4870X2 whilst easily outperforming it.
