DUAL ATI HD 4870

Can anyone tell me if it is possible to have dual ATI HD 4870 graphic cards in a current Mac Pro.

I had one delivered this week and I wish to run dual 30 inch monitors, the mini display port will not display full res.

There seems to be only 2 PCI-E Aux power ports on the Logic board and the cards require 2 each.

Starting to think I have configured it wrong...

Any ideas?

Mac Pro (early 2009), Mac OS X (10.6.2)

Is it feasible in your opinion to run this with a 4870?

It can't be over 75 watts since Apple sells Mac Pros with up to four of them installed.

Yes, at least for OSX. Windows may have problems with cards from multiple manufacturers. The NVIDIA GeForce GT 120 doesn't use any auxiliary power connectors.
