Big Iron: On Display - Are SLI/Crossfire worth it?

With the impending deployment of a new calendar (why, hello Miss January), a young gamer's fancy turns lightly to thoughts of higher resolutions, better anti-aliasing levels, and new DX10.1 effects. But something is knocking the luster off the lust faster than dropping Aunt Edna's fruitcake in your lap. Jacking up a single setting is dropping your framerate to a crawl, even with the latest drivers hot off ATI or Nvidia's server.
You've got multiple CPU cores and a fistful of dollarsRAM, and things still aren't remaining as smooth and speedy as you'd like? In short, is stuffing another video card in your box the way to achieve Nirvana? Chances are, if you're already sporting a rig with the aforementioned goodies, a multi-GPU setup is about the only way to get a performance bump. The question becomes, is throwing another couple hundred dollars at the problem worth it?
