Maybe the average card will clock like that and maybe it won't... We have to wait for end users to get the cards and test them before we really can state something like that. I will just say that Anandtech already has reported throttling in their review at 750Mhz... and at those clocks it still loses to the 6990 in a several games.
However, the thing is... even if Nvidia can sucessfully keep the cads alive via a current limit on new drivers -- that DOES NOT excuse them for using a poor quality, 4+1 VRM set up on their flagship card. It is unacceptable, and I think that is the main reason people are giving Nvidia a rough ride.
