No, most of the farm is made up of 1GB Radeon 5850 and 6950 cards that kinda suck for mining YAC at the current N value. The coin we're currently mining is still profitable, and our operating costs to run the farm are pretty high (in the 4 figures per day), so... 
May I ask what you mine with your 5850 and 6950 these days?
I have 2 of each and their power to hash ratio is just too bad.
