When you say 10, what are the units? Khash/s? Mhash/s? Note that
http://www.alloscomp.com/bitcoin/calculator.php will be your friend when trying to determine how much profit you're likely to get, and that it uses units of Kilo-hashes-per-second.
For what it's worth, if I pushed my laptop (circa-2008) to the max I would get about 5 Mhash/s, and I've already given up mining, even in a pool. It's just not worth the wear and tear on the machine when you're only earning pennies a day.
