I currently have 2 19" LCD's. I keep Cubase spread out between them. My two LCD's are running on an ATI PCI Xpress card. I really want to add a third monitor so I can keep the RME Totalyser on it (RTA, Phase meter, stereo graph, and both peak and RMS meters). I am guessing that I can just add a simple PCI graphics card to use for the third monitor? Originally I was thinking to get the same brand of card to keep the drivers all in the same family. Now I am thinking it might be better to get a completely different brand so that the drivers can actually be more seperate so one doesn't try and share with another somehow and create difficulties.
So my questions are....
1.) Can I add a PCI graphics card if I already have a PCI express card installed?
2.) If I can, are there any known conflict issues?
3.) Any thoughts as to whether or not I should get the same or a differnt brand based on my thoughts above?
