Stopping mining now is a very bad idea. This miner seems to be kind and not using his power at full capacity, hashrate is about 8-9 MH/s, this is not something we never saw with CPU-only miners. It is the last chance to mine with your CPU, soon it will be impossible.

I started to work on an AMD miner, I haven't previously done anything like this, hard to say how long will it take.
