    Yes you can. You'll need some molex cables to run power from the second optical drive bay to the card, however.

    I'm doing it in my 2006 Mac Pro with a 5870 and an 4870.

    If it were me, I'd play it safe with a PSU mod in the unused optical bay. Apple doesn't publish power rail specs for their PSUs, so to me, it's a shot in the dark over the long term. I would be worried about over-stressing the Molex feed.

    I would be worried about heat with those two 5870's. What is apples next card they are going to up in there?
