Why is the GTX 580 superior to the Radeon 6970?

[tweakboy]

Because they were first after 3dfx that did GPU. then ATI followed later on trying to catch up with dirty drivers.

Huh? 6970 and 6950 generally tested hotter and louder than the 570, though in most reviews, by so little so as to be all but negligible. This doesn't make it a bad card or anything.

Even anandtech had the 570 taking in more power but putting out less noise (not that common a finding in terms of power consumption): http://www.anandtech.com/show/4061/amds-radeon-hd-6970-radeon-hd-6950/24

What's your argument then? He said the 6900s are hot and loud, you say the difference is all but negligible and cherry picked reviews to support that claim. Is the 570 the new baseline, that if cards crossed they are considered hot and loud? What's your point?
