    Two video cards are very helpful for running games at high resolutions or for instances where you need to use more than two monitors at the same time.

    The gaming benefits vary, but are usually only very significant at high resolutions such as 1600x1200 and above. Realistically, dual-card solutions cannot double performance, as theoretically expected, over a single card. Gains of 30-50% are most common.

    Cons of having two cards include increased heat dissipation, increased power consumption, and driver issues, especially with newly-released games that need hotfixes or new driver releases to take advantage of both cards.

    And FYI, the above do not necessarily apply to dual-GPU solutions like the HD 4870X2, since the implementation is quite different, and driver support for such cards is usually better than for, say, two HD 4870s in Crossfire.
