Yes, I am getting ~1.2GHash/s according to my miner. I really don't know how much processing power would be required to do solo mining, and that is why I asked. Thank you for clarifying this. Therefore, I made the right decision to join a mining pool.
Now, will anyone help me with my real problem, the high number of rejected shares? I really don't want to waste electricity and the life of my GPUs on bitcoin mining if 40% of my shares get rejected.
Thank you in advance!
I see a increase on the rejected count when I'm downloading torrent (at full capacity of my crappy conection) and mining at the same time, but I'm getting only 300Mhash/s (1 HD5850).
