I do. I get 8H/s per core. I'm using the terminal windows miner in OP. I am using only 4 cores though. I think I recall the hashrate being something like 7.5 or 7.75 per core when I was using 6 cores. Do note that I am overclocked to 4.1GHz, however.

You should still be higher than you are listing on stock though. Are any other programs taking up processor time in task manager on your computer? Also download CPU-z and check that there's no downclocking going on. You can use coretemp to monitor the temperatures.
