all depends on the monitor. this needs to be a lot more clear with AMD's specs and web documentation. i know HDMI HD3D was limited to 24hz @ 1080p and the display port is limited to 60hz as far as i've seen. so you got max 60fps or max 24fps.
i don't believe AMD supports 3D at over 60hz yet but things may have changed with their new series of cards or drivers.
