I have read through a lot of the threads relating to multiple monitor set-ups and its seems a lot of people recommend the Matrox cards. I want to run two LCD monitors both of which have DVI connectors. The Matrox website indicates that a dual DVI G550 is $150 and an additional cable is required, the cost of which is not stated. The G650 card is a dual DVI card and requires no additional cables. The G650 card price is listed at $169. I don't know much about video cards, but it appears that the G650 is a higher performance card and would cost about the same or less than the G550 card and the required cable. Can anyone make recommendations between the G550 and the G650. Is there a better alternative to the G550 or G650 card if I just want to add one LCD monitor to my machine with a DVI connection?
