I am building a new system, mostly for 2d business applications. Unfortunately, I stare at the monitor for almost 6 hours a day so both my monitor and video card must be more than just throw ins from OEMs. I would like to have the flexibility to eventually have a two monitor system. I've done some research and am considering the GeForce II, G450 and Radeon VE. Please let me know which you'd recommend and why. Or if you want to suggest another option, please feel free. Thanks in advance.
