Hello, I was hoping to ask a question regarding my 2010 Mac Pro. Its currently got an ATI Radeon HD 5770 with 1x DVI and 2 x MDP. I want to connect 3 monitors but it turns out I'll need to buy 2x mini displayport to dual-link dvi adapters which retail at $149.00 Australian dollars each. So my question is, is it possible to buy a second graphics card instead of the two expensive adapters and attach my third monitor to that? And this leads me to my final question, what graphics cards do I have to choose from? I can't seem to find anything here in Australia that isn't from an international ebay seller and at the same time, I have no idea what I'm looking for. I hope to spend less than $300 to hook up my third monitor. My 3 monitors are Apple Cinema Displays 20" 1680 x 1050 (Aluminium) I really appreciate the help with this. I'm lost!
