Which card with two DVI ports for two Cinemas 30 inch?

I had to return high end 12 core Mac Pro because the ATI Radeon HD 5870 which came with it has only one DVI port and the two Mini ports with limited resolution, max. 1280x800.

Which card with two DVI ports do I need for Mac Pro to support two Cinemas 30 with resolution 2560x1600?

    I have a Mac Pro with a 5870 board that is running two Cinema 30" displays at 2560x1600 just fine. You need a mini displayport to dual-link DVI adapter, and you need to connect the USB connector on the dual-link DVI adapter to one of the USB connectors on the Mac to get sufficient power to run 2560x1600.

  • Each of the mini Displayports will drive to 2560 x 1600; but, you'll need the Apple mini Displayport to dual link DVI adapter, $99, to connect the Apple 30" Cinema Display. (the $29 mini Displayport to DVI adapter is single link, 1920 x 1200max)
