The solution I hear most about is to use a Maxtor G400 32MB Dual Head card. Be sure its a "DUAL HEAD" card. This one card has connectors for two monitors on it. The whole splitting of video is done primarily by the card. The one card solution by-passes conflict problems with two cards. As for using two cards of the same manufacture, I suggest scanning the manufacturer web site and contacting tech support. By the way, Maxtor card will be in excess of $150.00 US.
