Professionally Researched. (What's this?)

On One Hand: Dual Video Cards Can Be Fast

Having dual video cards in a machine with a dual monitor display means that each monitor can have a video card dedicated to it. This means that the full processing power of a graphics processing unit, or GPU, can be used for each display. This results in faster 3-D performance in an intensive 3-D application and possibly even faster 2-D performance in video and graphic design applications.

On the Other: It's Not A Necessity

Dual video cards are not a necessity for using dual monitors. Many video cards today have dual video outputs on one card. Should a computer user not need high-speed 3-D and 2-D performance, one card is likely more than adequate.

Bottom Line

If a computer user wants to play the latest 3-D games in a dual monitor setup or do professional graphics-intensive production, then using dual video cards may be beneficial. If a computer user simply wants to use two monitors for everyday tasks, then one card with dual outputs should be fine.
