Next to nothing (CPU mining). I guess I might as well stop mining altogether
join a pool & GPU mine too, something is better than nothing

, dont leave your PC on 24/7 with low mining rates.
I have two machines doing pooled mining (CPU, as I have no suitable GPU), and together they harvest around BTC 0.25 per week, even if they're both mining 24×7. C'm'on, dude
