Can a dual video card setup (2 pci express cards) output a quad-monitor display?

i am considering a quad monitor display for real-time stock monitoring and trading....just wondering whether 2 non-workstation cards (ie. ati x1650 pro) can be used in sli for a quad display or do i need to get a workstation card such as the FireMV 2400???|||yes. I think you should be able to do this.|||I am not sure, but another option you might want to consider (knowing that workstation cards are expensive) is buying a very large monitor (i have a 27 inch) it is actually a TV, and you can get very high resolutions, enough to where you can have four screens on one monitor and be fine.
