I tried to mine using my GPU it was doing on average 190-199 mh/s. It was making my room hot and probably damaging my computer. Fan was running at 85% all the time.
I recently got an ASIC Erupter miner which is going 333 mh/s and with low power usage and low heat as long as i keep the USB fan on it. I think this is the ASIC era going forward.
