just like you think they would - they also take the shock of the torque off the engine mounts a bit when you accelerate hard - if they are shot you might notice some more vibration at idle, but your engine mounts will wear out faster - that's a hard thing to gauge, so will it make a difference? sure. will you notice? probably not. I would replace them if I replaced the engine mounts or had the engine apart or had to remove them for some other fix.
