Is buying 3 cheap graphics cards better than a single high end card?

Is it possible to use Nvidia cards with SLI alongside AMD Radeon cards with crossfire?

Do I need the same brand of video card to Crossfire?

I've got an XFX 5850, and I'd like to get another to do Crossfire. Does this second card need to be an XFX or is any 5850 fine? The Sapphires, for example, are much cheaper.
