Power-Usage Benchmarks
Power use stays relatively close to the performance curve we have experienced, although the Radeon HD 5870 in CrossFire does show itself to be more power-friendly than the GeForce GTX 470 and GeForce GTX 480 cards in SLI.
We’ve seen impressive performance from Nvidia's GeForce GTX 460 when it's matched up with a second card in SLI mode. But how does the entire high-end GeForce GTX 400 line compare to Radeon HD 5000-series cards? We test them all in several popular games.

BUT.. i would have preferred 2-3 way SLI with GTX460's.
