Well considering how amd were pushing this as something that could be achieved with a firmware update on some screens already on the market the 48hz minimum rate is incredibly lacking to say the least.
There was a lot of bluster from amd about freesync over the past year and the launch had all the impact of a wet fart. No crossfire support, people had the monitors before they could get the drivers, and it seems that online stores are reluctant to post the freesync working rates in the monitor description as the low end of them is pretty abysmal, and the low end is something you'd expect to be much better as thats where games get choppy and that's one of the points of gsync\freesync.
The best it ever could be is meant to be from 9-240hz, i doubt many expected that on launch, i think plenty expected a low end starting around 20 or 30hz though as it would be very useful for games that tanked that low in fps.
Waiting game i suppose, not all that impressive since AMD were saying review sites would probably have freesync monitors in September of last year.
