here some more nice insiders information about the 6970 single and CF;

According to Neliz @ gathering of tweakers forum:

''6970 is 50% sneller in Furmark dan een 580, om even te laten zien dat er niet (of minder) aan throttling doet.

tevens zie ik een benchmark met 87fps @5760x1080 in batman:aa

6970 CF zou ook tussen 10% en 50% sneller moeten zijn dan 480 sli op die resolutie.
6970 is tussen de 10 en 30% sneller dan de 570 in de meeste benchmarks''


Translated (dutch is my mother tongue so sorry for some misspelling):

The 6970 is 50% faster in Furmark than the GTX 580, to show that there is non or much less throttling involved.

Furthermore he saw a benchmark with 87FPS @ 5760x1080 with Batman:AA.

The 6970 in CF will also be between 10% and 50% faster than the GTX 480 in SLI with that resolution (5760x1080).

The 6970 is between 10 and 30% faster than the GTX 570 in most of the benchmarks.
