I just purchased a Radeon 4870 from Apple but when I hook up 2 monitors the desktop always comes up on the mini display port & not the dual DVI. Is there a way to make the DVI port my desktop in a 2 screen setup?

If you open up the display manager you can switch which screen the menu bar shows up on. It shows pictures of two screens next to each other and you can drag and drop the bar onto the screen you want to be your main screen.
