If mining Bitcoins is not giving you much back try mining litecoins there are numerous pools doing it, but then I found ltcrabbit. Very easy to setup, they even provide a USB run operating system running Linux just to mine with, or a version of CGMiner with an easy to edit batch file. Litecoin mining can only be done on a graphics card. AMD performs better than Nvidia, but each will mine.
It is a Pay Per Share pool, different to most pools. This makes payouts different but not necessarily worse compared to most pools. The rewards are bigger than bitcoin rewards. I mined 0.05 LTC in my first 24 hours on a mid spec AMD card, and the same agin today. They have stratum servers in USA, Europe, Hong Kong and Australia. If you are resonably new to mining you will find it easier to setup and mine than other mining sites. Go and have a look go here.
