Now if you're talking about having two video cards in SLI or Crossfire, thats different. With two or more SLI/Crossfire ready video cards, you can connect them together so both cards perform about half the work, so theoretically you should get twice the performance with two cards over one. However it doesnt perform that well, so you may have around 30-50% improvement (more or less) depending on the game/program your using.
