Sorry for misunderstanding and when u think of dual gpu cards: 4 x 1,5 gb = 1,5 gb effectively!!!! So, it is even worse from what i know. It is the same as doing sli with 2 sli. Oh my god how bad. Correct me, but dual gpu is sli with better bus values, so it is less problems than normal sli, but still not using fullram.

So you throw with houses on ants!! :) correct me if i am wrong with the dual gpu thing, but it is never 6 gig in any sli config. The card should have 6gb each to get this 6 gb. Never sum up the 2 cards. It is simply wrong!!!!!
