It really depends on what your PC can support. Do you have two open PCI Express slots? If so, I'd get a couple of these: http://www.newegg.com/Product/Product.asp?Item=N82E16814108147
If you want to run MULTI-DISPLAYS ( and not just "clones" of each other ) go to the Nvidia website and download their software program ( for Free ) entitled . . . nView Multi-Display Technology http://www.nvidia.com/object/feature_nview.html Very simple. And very effective!
