Sadly this will not work in Eyefinity/surround mode as they create a single large surface, so to windows this appears as 1 monitor, with 1 refresh rate, so all displays require the same refresh rate.
However if you wanted to play a game on a single monitor, you could run 60/120/60hz as monitors 1/2/3, then switch to 60/60/60 when using eyefinity/surround mode.
All ATI series 5xxx and above will drive 3 monitors from 1 card, and only the latest nvidia 680 is able to run 3 monitors off a single card, all previous generation nvidia cards would require an additonal nvidia card in SLI configuration.
