Hi guys, I just received a 23 inch apple cinema display from a friend. I currently have a macbook pro (2008 uni) and a 24 inch LED ACD. I was wondering if I could create a diy vidock for much cheaper: http://www.hwtools.net/Adapter/PE4H.html Would this even be mac compatible, I was thinking I could use an nvidia gtx 120 (from apple) with a mini display port on it for the led display. Also, would connecting a card through the express 34 slot slow the speed of the computer down? Thanks for your help!
