Outputting to five displays

Our college is attempting a multimedia show, where a single computer running QLab needs to output different videos to five different displays. I've been able to put two stock GeForce cards in our 2008 Mac Pro. But I haven't found any other video cards (without a separate power cable) that I can add to the Mac Pro. The closest I got was the XFX One, which the OS (10.6.8) seems to recognize but won't initialize. I tried a BlackMagic dual HDMI card, but even with the drivers installed the system doesn't seem to recognize it outside of BlackMagic's own software.

Any suggestions?

XFX and PC cards lack EFI type ROM though there may be a way to but a ATI 5770s from Apple would work

I had a chat with Apple tech support today. About the only solution they could offer was to get an ADC card and then attach a splitter to it.

But I finally found a solution: we're going to use an iMac with Remote Desktop to manage the Mac Pro. That will leave all four of its DVI ports free for the projectors.
