Yeah, if it's only slightly louder than a 580 it will be an amazing feat. The problem I'm seeing with these cards is the price/performance. At 600ish mhz, if that is infact their speed, they will most certainly be slower than the 6990 and I don't see any way possible that Nvidia will charge less than what AMD will be charging for the 6990.
It's going to be interesting to see the discussions between camps when Nvidia has the cooler/quieter card and AMD has the faster/louder/more power hungry card. I foresee a lot of people changing their tune compared to what they were saying this time last year.
Edit: Here as some benches of a 6990 vs 580's in SLI at the supposed 590 speeds:
