I just installed the ATI 5770 in my early 2009 mac pro,  I was told it would run three displays.  I want to run two DVI displays and a DVI connected cintiq 24HD all at once. I was told at time of purchase this would work? right now it doesn't work together but everything works on its own.


Follow up question I have the original video card that came with my computer, can I install both video cards at once to fix this problem?


I'm not super techincal so bare with me if I'm missing the obvious.


Thank you
