    GTX680 performance preview at HKEPC

    According to the article, the GPU base frequency will be 1006Mhz and GPU Boost frequency will be 1058Mhz. However, in games, it will boost even further to between 1097Mhz and 1110Mhz. So the whole picture (from my impression after reading the article) will be like this: OCCT/Furmark...
