In my experience, you have to be careful with high aggression settings. High aggression settings do bump up the hash rate that is reported on your end by your mining software. But what pays is your share acceptance rate at the pool where you mine. And I've found for my 5850s that high aggression settings actually throttle my share acceptance rate. I played around with this when I had two 5850s, and I found that I got the optimal share acceptance rate with one card set at 7 aggression and the other at 9. Anything higher than this and my share acceptance rate started to go down rather than up. Perhaps you won't have the same result, but you should look into your share acceptance rate and make sure that higher hash rates on your end are in fact translating into higher share acceptance rates. Due to variance in luck, you have to let your rig run for a while at any setting to make sure that the change in acceptance rate isn't just due to luck, so it is tricky and time consuming to tune your cards this way. In fact, to screen out effects due to luck, you probably want to mine for a while at one setting, calculate your share acceptance rate, then change the setting, let the cards mine for a while, then change the settings back and let the cards mine for a while at the old setting. But I think you can get a rough feel for the acceptance rate while you are rough tuning without doing this. I now have four 5850s, and I have one set at 7 and the other 3 at 9, but I haven't had the time to tune all four for max share acceptance rate. Anyway, just tossing this out as something to consider.
