Received my miners today and they're now up and running without too much difficulty in their setup.  Pool is showing them bouncing around between 2.5th/s and 3.5th/s which I believe is probably normal.  Sound levels are nonexistent in the room with my GPUs.  They are pretty much exactly what I expected (having to run multiple instances of the mining software was the only real surprise).  Granted I wish mining profitability was a little better currently, but you can't have it all.
