Keep in mind that if you upgrade your video card you may also need to upgrade your power supply. Be sure to read the required specs of your potential video card, then check against the power supply size of your current system..you may need an upgrade. The good news is that a power supply upgrade is not all that expensive.

I am one of the full-time online faculty members, and we all have 4 monitors at the office. It is very helpful and efficient when grading, posting in the discussion forums, and sending progress reports to the counselors. I also have dula monitors at my work station at home. Again, very helpful!
