Do the math on how much extra income hundreds of people are getting, and then answer that.

Also, I didn't want to say anything at first since it could have been an anomaly, but I've now realized this on four separate cards - my GPU usage (and thus hashrate) has always fluctuated like a small sine wave from 99% - 90% , after this patch, they all stay a straight line 99% , so that's way more than a 3% increase in hashrate for me.
