I use nTune, not for overclocking, but for the quick check of temps and very minor look see of things.
For using it as a tool for overclocking your system. No it is not the best. It is generic, to the AMD platform.
If you insist on using the easy button, try what the maker of your board supplies. That would be a step up. Not much,but better then nTune.
AMD with about an hour or much less can get you the same results as nTune and be much better.
You can get 2.4 out of that chip without much hassle. 2.2 if your lazy or don't want to take the time to develope a nice overclock.
Good things come to those who take the time and fiddle. Take the easy button and you will not be as happy.
