This CPU has been, is and will be in my ASUS F3Jc laptop. It's quick enough for my work in Windows XP and Mac OS X and runs fairly cool. To reduce energy consumption I've installed Notebook Hardware Control (only for Windows) and reduced the vCore in stressed mode. Normally it would run at 1,215V when it's clocked at 1666MHz but I configured it at 0,95V. Unfortunatly I can't set it lower but it shaves off almost 10C CPU temperature in stressed mode. Not to mention the battery lifetime .
