Maybe DistrRTgen? It is for searching after weak hashes and pretty useful (yes the "Rainbow Tables" will be publicly available). You do not pay for the power bill IIRC, so it might be worth consideration (others must keep the higher GPU load in mindbecause of the power bills). On a sidenote, there is very little lag while I am typing this. In fact, only scrolling does so that is quirte a difference compared to the WCG GPU WUs. (toast) I will still run the DistrRTgen WUs only a few hours per night though, because of the power draw.
