Frugal power-draw is a major feature of the 5-series GPUs. The HD 5850's under-load figure is the lowest of the bunch, not surprising given the rated TDP of 151W, and even two cards draw less than the single-PCB Radeon HD 4870 X2 and GTX 295s

A direct result of lower board power and an effective cooler is decent temperatures all-round.
