I have a desktop pc that is sporting a Phenom x6 and is overclocked to around 3.8 Ghz and this Acer AS5560-Sb613 laptop keeps up with my destop with no problem. I am a graphic designer and use Photoshop and Corel Draw. The specs from AMD for the CPU say that it overclocks a single core to 2.4 Ghz on high demand
