in that case you can increase the clock speed and also increase one of the intensity or powertune settings this will usually give noticeable increase in hashrate. just ensure everything is getting enough air. as for fine tuning someone else will surely help you.
your definition of "good" all depends upon how much power you are using with that hashrate. there are myriad options to tune & fine tune your hashrate with GPU's but having a look at the documentation and forums for sgminer would be a good place to start. in the new version you can even change...
I see, considering drk is outpacing ltc thats not likely to happen I know. I am having a problem with sgminer however, both x11 pools give me rejected shares as low difficulty? the --diff command line doesn't seem to work either. unsure whats wrong? ASIC's are ticking along fine.
