I don't know how different overclocking an AMD cpu is compared to some of the Intels, but providing you have a decent cooler on your cpu (preferably not stock), all you need to initially try out is to change the 'FSB' in the bios. I'd recommend that you look into pushing your cpu further (3.0 and beyond), since at 2.8 it will hold back most of the newer gpu's.

I think your psu should be ok, though I am not familiar with the brand name. If you have had this unit for sometime then it won't be as efficient as once before. I personally regard the psu as the most important component you can buy, and although it should in theory be sufficient, I'd still be inclined to keep an eye on it with maybe a view to upgrade it at a later date, sometime in the not too distant future. If, on the other hand, it's relatively new and the brand is half decent, then perhaps it will suffice.
