I have read through some of the threads and Im not positive of what will work. I would like to add this 4890 to my new Mac Pro http://www.newegg.com/Product/Product.aspx?Item=N82E16814102841 I already ordered the 2 power connectors from ATI. Will this card work and power my 30" display ? Also can someone list the exact files and in what order Ill need to use this 4890. I look through some other threads but some of the files had edits and updates on them. I just want to be very clear.. please do not Flame. The Mac Pro arrives Wed and I dont want to screw this up!
