I've been reading some forums saying I have to install a PSU to run the second video card since the Mac Pro won't take more than 300 watts (for the PCI slots) and some wire mambojumbo that i have yet to get any specific info about.
I'm not exactly sure what your goals are...but with most Mac Pro's, you can install 4 video cards. If each video card has 2 DVI ports...you can connect up to 8 monitors. Obviously if the video cards take up two PCIe slots...you won't be able to install 4 cards.

So with this being said...if your main goal is to run a lot of monitors from this Mac Pro...just install more video cards. If you want to run two 5870's in Crossfire...not sure you can do it.
