    If you're using applications that take advantage of nVidia's CUDA (parallel processing) technology, then yes. Adding a second card doubles the number of available CUDA cores. If your app doesn't use CUDA, then it would need to be specifically written to make use of multiple graphics cards in order to see a significant benefit.

    Aside from that, having a second card can give other benefits. Aside from supporting more monitors, you can improve your system's performance on even a dual-monitor setup just by using a separate video card for each screen.

  • You really need to check whether your key applications support more than one card, unless it is just a matter of running multiple monitors. Mathematica 8 recognizes 2 GPUs without difficulty in its OpenCL and CUDA links, but not all CUDA code uses more than one GPU, for example.

  • Certain CUDA applications should scale in performance with multiple gpus such as Matlab and Mathematica, both of which have CUDA accelerated features.

    You can also have two of these cards in a Mac Pro to drive up to 4 displays

  • Word to the wise, very inconviently so, you can't run a 2nd NVIDIA card in the same machine that isn't this one. I tried running a GT120 along side to drive my 3rd monitor and caused random colossal crashes. Apparently the Cuda drivers can't tell each other apart. I had to go back to my dual GT120's to drive my 3 displays, not wanting to purchase ANOTHER Quadro 4000.
