I purchased a ATI 5770 card in order to use FCPX.
This new card has 2 mini and 1 DVI port.
In the past I have run 2 old cards to drive 4 monitors with no problems.
For optimal performance, I understood I would just run 3 or those monitors to my 5770 card and not use any of my older cards for a 4th monitor.
I realized to get all 3 monitors to work off of its 3 ports I needed to buy an:
“Active MiniDP to Single-link DVI adaptor”
I still cant get all 3 monitors to work at the same time with this suggested adaptor.
Any guidance would be greatly appreciated.
I actually own (6) LG monitors that are all 1920x1080.

Instead of the adaptor I currenty have… should I be looking for (2) Active MiniDP to DUAL-link DVI adaptors.
From an optimized performance standpoint… would you advise me against buying an additional 5770 card to run my other 3 monitors for a total of 6 monitors?
I would love to gain the desktop real-estate but don’t want to fry any circuit boards or burn up any Ram in my MacPro 1.1
All DVI's, all with 1920 x 1080. Looks to me you have an easy solution. Two of those active Accell B087B-006B for each card for 4 of the monitors and the other two plugged directly into the remaing DVI ports. With 1920 x 1080 you should not need dual link dvi adapters.
Each card has its own video memory and power adapter and can handle three monitors so you aren't going to fry them. I assume your power supply can handle the load but I cannot be definitive on that.
One thing I am not sure of though is these cards are double wide so there is the possibility that one card could block access to the pci slot next to it. I have a 2010 mac pro 5,1 and slot 1 for my 5870 is actually physically wider than the remaining three slots.
From a cost point of view, if the cards you already have can handle three of these monitors why get two 5770?
I am not sure you will see a "performance" difference. I guess it depends on what you intend to use all these for. But there is the question of a 1,1 pci buss speed. I am not sure the cards can run full speed on 1,1.
