Two Graphics Cards?

I think i've seen somewhere that you can connect two graphics cards together to work in parallel. Dramatically increase your graphics capabilities, or something.

Is there truth in this? If so, any good articles? Links? How-To's?

Consumer cards? There was SLI-type support for graphic cards way before SLI came out, and they always have been highend graphic cards. They cost a small fortume and they never had support for DirectX whatever. They are so powerful they would fuck your game up the ass and beat it across the fucking earth because it is not worthy of such a beautiful piece of hardware. http://www.theinquirer.net/?article=12599

And there is one that I heard about, but could never find that could link up to 6(?) of the same type graphic card up for extreme polygon and texture rendering in 3dmax or whatever (Pixar highend rendering)
