with 10 L5639s (df and oced to 3.6Ghz),how much income from mining XMP

Quite a bit, I wouldn't dare to speculate on a quantitative figure. At least a few blocks a day on average. Question is, can you make a return on it, since it looks like (based on the the OS, W7?)these CPUs would be running in 'desktop servers' that you probably purchased.
