Thanks virtualreality69 !
Yeah at one point I was doing the same. Trying to squeeze every last hash I could out of my 270. I finally got smart and starting playing with a ltc calculator and realizing the it really wasn't netting much income/ltc coins for the extra 300-350 watts. What's really cool now is that I can keep mining ltc with the difficultly increase in the last week or so. I guess what's hard to grasp is that in the gpu mining game, is the hash/watts is a huge factor. Most small gpu mining people like me want the most hash rates we can get off your hardware.
Low clock speeds and under volting is where it is at.
