I've got an early 2008 mac pro that I'd like to drive three 30" monitors with. I'm not concerned with gaming performance and want three full-resolution screens (no mirroring). The monitors' interfaces: (1) DL-DVI and (2) DL-DVI / DisplayPort. The Mac Pro already has an AMD Radeon HD 6870 2GB installed and driving a single 30" monitor. So my question - does anyone know of a way to get the old MP to drive these monitors or is it time for me to put the old box out to pasture after five good years of service?
