Does anyone utilize SLI with their graphics cards?

[Fletcher]

Since I posted about my graphics card's lovely ability to heat up in my system, I've been googling cooling solutions and whatnot. Then I came up against a 2 and 3-way SLI method.

As far as I know, SLI or Scalable Link Interface (wiki link) is basically where two or three graphics cards work towards helping the main graphics cards. Think of it in the same way as a CPU with dual or quad cores, the more the merrier. In theory.

So, does anyone utilize SLI or similar configurations in their rigs? I'm strongly considering a 2-way SLI with two GeForce GTX 470's for smoother performance, prepared for big games and I hope though not anticipating lower temperatures.
