What single nVidia card will drive three monitors? [closed]

The GTX 590 will run 3 monitors fairly well. I'm linking a test done by Tech spot where they bench-marked 11 different games on a unified three monitor setup using the 590 and a Radeon HD6990. The results vary significantly by game and resolution, but the point is that it can definitely do it. They also make note of how dead simple setting it up is:

A few more notes on triple monitor gaming setups... We applaud the ease in which it is possible to setup multiple-monitor configurations. Both AMD and Nvidia have excellent setup procedures and we ran into no real problems when configuring the Dell monitors.

If anyone has more info on other 5 series cards please add it. I don't see any reason the 560 won't handle 3 monitors, it may not put out the same frame rates but it should still work. One final note: this is a dual GPU card so I don't know your reasons for avoiding two cards in sli/crossfire (possibly power?) but I figured it was worth mentioning.
