The Radeon HD 7900- and 7700-series cards have already shown us the 28 nm manufacturing node’s implications for power. AMD claims its 7800s are similarly efficient.

At idle, sitting on the Windows 7 desktop, both 7800s deliver the lowest system power results of the cards we tested.

In addition to their low active idle power, the 7000-series Radeons benefit from a suite of features collectively referred to as ZeroCore. When a display connected to one of these cards drops into standby mode, the card is able to spin down and shed another 10 W or so of power consumption. Compare the Radeon HD 7800s to Nvidia’s GeForce GTX 580, which drops a single watt, and still consumes more than 40 W as our test PC sits idle. 
AMD’s Radeon HD 7870 uses significantly less power than Nvidia’s GeForce GTX 580, while achieving similar results. That comparison typifies what we’ve seen from some of the other 7000-series boards: competitive performance at markedly lower power.

low settings were benched at the lowest resolution
mid settings at 1920x1080
and the highest at 2560x1440 (and not 2560x1600)
i mean most of us play games in the 1920x1080(1200) range, and if we are spending 200+ on a gpu, we will have about that kind of monitor... while if you have a 2560x1440(1600) monitor, you aren't wasting your time with these cards, even if its for crossfire.
what im saying is i would rather see the 1920x1080 resolution get the highest possible settings, as thats what most of us who want to max the settings will play at.
i mean when will it be launched in market
Looking at the performance graphs, 7870 performs very close to 7950 which has 40% more SPs and a 384 bit memory interface. I think AMD reduced the performance of 79xx series on purpose so that they can release a better card just before the launch of Kepler.
It is there in the first page. "you won’t be able to buy the card until at least March 19th, AMD tells us."
what a card !!!
DAY 1 BUY !
And all of this can be had for $350. Without question the best deal in the lineup.
btw, none of the AMD partners use blower design cooler? wtf!!! Blower card is what I need! Especially my existing mid tower ATX aluminium case are old design from way back in AthlonXP.
