Hey all, I want to drive several monitors from my Mac Pro, but I don't want to spend the money on an expensive video card. I have no desire to play computer games, and I don't do any rendering or graphically intensive applications, I just develop software and would like a bigger canvas. I have an ATI Radeon HD 2600 in the computer right now (which came with it) and I am looking to drive three more displays than that card supports. What are my most inexpensive options? Anything cheaper than flashing a 4870?
