I have a samsung np305e5a-a05us which has an amd a6 processor. the gpu on the laptop is rather weak and am wondering what my options for speeding it up are. I have heard that with these "fusion" products, DDR3 RAM speed is key. Would upgrading to 1600 or 1866 help at all? I've heard that these processors only use 1333MHz speed so no clue. I've also heard that the cpu can be overclocked but have never tried. Any suggestions?
