I'm sorry if this is covered elsewhere and I missed it - I've been searching all over online and could not find anything. I recently purchased a used Mac Pro 1,1 with an ATI Radeon HD 2600 XT. I would like to run a 3-monitor configuration as I previously had in my Quad G5 PowerMac, but am finding it quite confusing to find a card that will work in this new system. Is there a compiled list somewhere of cards that would work in the Mac Pro 1,1 and is there anything to look out for if I want to use the additional card as a secondary card? The 3rd monitor is just being used to display iTunes, Entourage, stickies, etc - mostly stuff I like to be able to quickly access from time to time while doing web development on the other two screens. That being said, I'm not looking for anything "killer" and I saw that a secondary card would only run at 8x, but would like to have a dual DVI card so that I COULD hook up another monitor down the road if desired. Any recommendations or suggestions greatly appreciated... Thanks!
