0.007 BTC per MH and day... this profit barely covers a 0.10 USD/kwh rate. I keep my rigs working because they heat my house nicely, but this is the only reason now.

How is your efficiency on your mining Rigs? I generally have 500 Watts per MH of hashing power, which translates to roughly $4/day in power at 11/kwh electricity rates.

Same results, about 0.5 kw per MH. That's 5 cents per hour per MH/s, so 1.20 $/day for every MH/s.

What HW are you guys running? i'm still running 5 series GPUs and my rig eats 650w for 1Mh/s (5870/5850/5770/5770).

I have a weird mix of 5xxx and 7xxx.

I have now got a 7950 added (7950/5870/5850) whats the best config? i have: -g 1 -w 256 --thread-concurrency 8000 -I 15,18,18 --auto-fan --auto-gpu --temp-target 70

edit - i'm getting a lot of HW errors with the 7950 (i think this is the thread-concurrency being wrong though)

As hashcows has vardiff, I used multiple instances of cgminer - 1 for each card in the system. This allowed me to tune each card individually (7850 & 5870 & 5770) and for each one to have its optimal difficulty.
