Hello, I have a Core Duo, 20 inch iMac with 256 vRam and 2 Gigs of ram, I would like to know if I could attach it to a 30 inch Apple Cinema Display, I couldnt find anything about my model and adding a 30 inch monitor to it but I know that the 24 Inch and stuff can support it but I would like some confirmation before i make the purchase, I need the extra screen space for Logic Pro.
