I have a GT120 and a GTX285 running one ACD 30" and two ACD 20"... I'm selling my 30" to get the all new ACD 27"... I'm also thinking of selling off the two 20's as well... Does this also mean that I need to sell my GT120 and GTX285 and either get a 5770 or 5870 to make the ACD 27" work? What are my options? I know the 5870 is not available... I'm not a big gamer or graphics designer, but love the best!
