Mining with 25Mhash/s will give you 0.40$ a day at this difficulty level... I bet it doesn't even cover the powercosts...
I wonder how much my low-end cpu/nvidias are doing. I got 4 or 5 cpu/vm hashing at home each doing maybe 10-20MHash/sec.
Plus 5 Nvidia cards each doing about the same to a 'high' of ~90M/sec. LOL. I think all my cpu/vm/nvidia miners combined are doing less then a single beefy ATI card. Boy I would be so pissed if I was playing utils.
Not even including the cooling required for all these extras.
