I have ordered a card like this. I wasn't sure where to direct my question, but i was hoping anyone would have some experience in this area, since i am having a 30 inch older cinema display. And if anyone have seen this problem and dealt with i would love to hear some fixes Hes problem was the machine would only boot to the white screen, then stopped ? Just for future reference or anyone else who might be having a similar issue. This problem turned out to be related to the monitor. We used a 30-inch Apple Cinema Display. When that is plugged in, the card doesn't work. When that is diconnected, and replaced with a Dell screen, the card works fine. The monitor works fine with the Radeon card, but not the GeForce.
