I have an early '08 Mac Pro with a Geforce 8800GT card which has a dual-link DVI output. I currently have a 30" Samsung DVI display but I want to replace it with the slicker 27" ACD. Given that the 27" ACD is mini display port only I wanted to know what I should do: 1. get the ACD and a mini display port to dual-link DVI adapter of some kind 2. get the ACD and a 5770 upgrade kit I think that option 2 is the better of the two but wanted your thoughts. Will the 5770 even work successfully in my early '08 MP? Thanks!
