so i'm gonna be getting a gtx 680 probably some time next week and i currently run a triple 120hz monitor set up for 3D surround. Now i know these cards can power upto 4 screens but they only have 2 x dvi so am i right in thinking i need a displayport to dual link dvi adaptor? if thats the case, due to the price (about £80) think i'd simply rather just skip it for a little while and just get another gtx 680 for sli which would then provide the extra dvi outputs like i currently have now
