can someone please tell me is it really truth! manufactured overclocked 6870 (XFX HD-687A-ZNBC Radeon HD 6870) better than non-overclocked 6870? can you just enable ATI overdrive to make settings higher?

You can overclock most cards to the factory overclocked standard or higher very easily. Generally there is no reason to buy factory overclocked. Just do it yourself.
