Need inexpensive video card for mac pro 2007 for 3rd LCD

[maclamb]

I have a 2007 Mac Pro (dual quad 3.0ghz) and its video card (Radeon X1900) is driving two monitors now (19" and 22").
I would like to add another monitor and am looking for an inexpensive video card. It will be for email , Word docs, design palettes, no gaming.

Any suggestions?

Or, is there a way for the current card to drive more than two monitors?

I would check either otherworldcomputing.com or the marketplace. Neither option will be very inexpensive, though, since Mac Pro cards sell at a premium no matter what.
