and i have stuttering with 6950. despite it runs EVERYthing at max (and then some more - i added extra stuff into skyrimprefini) and then some ultra, while running, it stutters occasionally.
i read skyrim forums and saw that this was an issue affecting many cards, not just 6950 or ati - nvidia people too.
so its something related to skyrim. someone said that a patch regarding graphics was going to come out soon. probably this.
