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.
And what about the hardfork witch slighly changed algo?
Miner included in wallet will include this change and private gpu miners will need to redesign their software.
Smart change in algo will sloooooooow down this redesign.
