For their professional series of gpus they offer premium mosaic which allows up to 4 monitors on a single card[1].
AMD allows up to 6 monitors on a single consumer card with Eyefinity[2].
Of course through the use of splitters and multiple cards it's possible to attach more monitors. I've personally setup a 12 display system off a single card. There are of course performance limitations when you only have one gpu and a large grouped display.
For what it's worth I've had an easier time setting up multiple monitors in Linux then I have on Windows.
