Agreed - like mining! Anyone else mining DGB-Qubit on AMD? I'd like to know if the hashrate fluctuates heavily for you too occasionally.
I'm mining qubit on my two Radeon HD 7850s, the electricity costs more than I'm making, but the extra $20 or so per month isn't a big deal to me. I do the mining for fun/enjoyment. Below is my mining info.
I'm not running the cards hard at all. I used to push them hard on scrypt and they would hard lockup after about 20 days. As you can see, it's been running 24x7 since Nov 6 at the current setup. I could probably push them a little more but it's not that important to me, like I said, I'm mining for the enjoyment, not to wring every last coin that I can get.
I don't pay alot of attention to the hashrate fluctuation. In fact, I rarely log on to check it (once a week maybe?). I just check the mining page to make sure my hashrate is somewhere between 4M and 5M, that way I know it's still running.

PS: if you notice a few letters missing, from the words "Settings", "Intensity" and "Experimental", that's because I had to edit it - the letters in brackets were messing up the formatting
