Pretty much any card will run dual monitors. You only need an eyefinity capable card if you are planning on running 3-6 monitors. If both of your monitors are vga only you may need to pick up a dvi/vga adapter, like the one fantastic250 suggested (although some cards come with an adapter like that). When you say "work purposes only" I assume you mean business apps, outlook, word, excel, and the like, not photoshop or autocad and solidworks and such. If you tell us your budget we can recommend some cards. Also, you will need to make sure your psu can supply enough power to run the card and your system.
