    No, it's converting in the wrong direction. This is to connect a monitor that requires a DVI-DL connect (most 30" displays) to a machine that only has Mini DisplayPort output (all recent Mac laptops, MacMini, and iMacs).

    You may not need an adaptor depending on what video card is in the MacPro -- is there a small not-quite square port on the video card, besides the larger DVI connector? Wikipedia has pictures of what MiniDisplay Port looks like. If you have that port, you'll be able to connect new Apple displays without an adaptor.

    Gefen and Altona both make DVI to Mini Display Port converters, but it a quick search didn't find them on Apple's site -- you might need to try Amazon or some other store.

  • A dual link adapter is supposed to allow you to drive two (2) DVI monitors from a Y cable. Both monitors would be seeing the same video - a mirror of video images on the two displays. This is useful when you need to drive a monitor and a project at the same time from a single mini-display port. However if you don't need to drive two monitors, you should be able to use lower cost adapters or cables that convert a mini display port to DVI output. Apple's graphic cards for the MAC Pros now have both a mini display port and a DVI port. You could just as well upgrade your graphics card to an ATI GT120 for example that has both.
