*disclaimer* if this is already widely known then I apologize and you can call me a noob* Alright I just found out the most amazing news! The Nvidia GT 120 works with the 2008 Mac Pro despite what Apple.com says. This is good news for us 2008-Octo-core owners who want to use an LED cinema display and save some money over getting the ATI 4870 card OWC has tested it and so have several other guys here http://blog.macsales.com/602-testing-those-new-graphics-cards A guy also tested the GT 120 with the older ATI 2600 and they both work flawlessly together. This made my day and I'll be purchasing a new led cinema display and GT 120 graphics card once I get my tax return. 2008 octo-core owners rejoice! w00t!
