Like the unlucky coincidende of his review showing the GTX590 being faster (all resolutions)
Well, you said its faster at all resolutions.It isnt.
Its faster at low ones, and ties/slower at high ones.So you cant say "its faster".Cos it "depends" on the conditions.And realistically you have to admit that these cards aint gonna be used at 1024x and neither 1650x most probably.I know its hard pill to swallow.ITS NOT FASTER :-).

In a dual GPU solution, that costs $700, that is big, hot and power hungry, who really cares about perf. per watt?
Anybody who cares about heat output and noise of their system.For example.
You put waterblock on a card A that draws 100W and card B that draws 200W, in the latter example you will have to turn up fan on your radiators.
Same goes for any decent aftermarket cooling.Idle wattage is important also, low enough idle gives you silent system in non gaming scenarios.
I know i know, nvidia has put bigger fan on their reference cooling.But im gonna point you to the 700$ bit, if people arent concerned with power consumption due to the electricity bills, they most probably can afford arctic cooling silencer or a waterblock ;-).

As to the temperature, i honestly missed that bit.Yes.Nvidia wins, by one celsius on one of the GPU`s which isnt in boundaries of a statistical error at all...
Besides if you dont use same cooling, results arent really comparable.
Yes in idle it looks better for nv, but higher idle temp(still lowish) while consuming less power on the ati card clearly indicates different fan/and its temp curve.

Quieter, cooler, more all round performance, higher OC (26% vs 10% of the 6990), same price and... 7.0 score. Go figure.
The CARD isnt cooler, it exhausts more HEAT into the system than the 6990, it was proved in anands test for example.Besides its pure physics.Uses more power,generates more heat.Then there are of course those temp shots on this french website which clearly show that the card is hotter (while the GF chips are a bit colder,bigger fan).
TPU is european website, price isnt "same" also here.
As for the OC capability, it gets dangerous on the 590 ,a few of them blew up, and not only at 1.2v, 1.025v was one of them.Besides for ocing, GTX580 or HD6970 are much better suited.
And dont get me wrong, i wouldnt buy any of them.
580 or a pair of 6950`s .Thats the only thing that makes real sense.
