Re: 4 monitors on 1 computer?
If both cards use the same drivers you are set to go.
After you install the card just right click on a your main screen then your ATI control panel and set the 4th screen up just like you did the 3 screens,
There is no magic to it and is vey easy to do.
I have had 2 work computers running with 4 monitors for years.
Just remember, you can not use all four screen if you enable Crossfire.
