I have been running a bitcoin client for nearly a year now and sadly I've generated no bitcoins

So I figured its time to get in on the market by simply buying my way in and seeing where it goes from there! My computer has an i7 920 overclocked to 3.6 GHz, so perhaps I was doing something wrong with the bit torrent client? I tried to get in on the CUDA action with my Radeon 5870 but I never got everything running properly.
