hi all just wandering, a friend of mine has a 5970, he did a graphics update today, and now his gameplay seem jumpy, his usage on the second gpu dosent seem to be getting used, i cannot check for him as he lives nowhere near me, and i dont have xfire so i cannot compare my settings either, is there a setting in catalyst control centre to enable xfire, also he says the gpu and memorey clock settings on the second gpu are both 0, any help would be appreciated.
