I have a GTX-580 TriSLI & TriMonitor setup that I'm happy with, but I would like the "Process-bar" to extend to all 3 monitors, so I have the "START-icon" in the lover left corner of the first monitor and the "TIME-icon" in the lower right corner of the third monitor. I know it's possible to do this with 3th-party software, but I was wondering if it's possible to add a ATI FirePro 2460 (4x mDP output's) in a "DualBoot" config, so I'll use the FirePro card for normal BusinessTask's while the 3x GTX-580's are folding and if I want to play games I can reboot the system and use the 3x GTX-580 as a TriSLI for games while the FirePro isn't doing anything?

Any input is welcome!
