To make a short story long:
The Lenovo G505s offers sufficient power to perform most of the tasks. Moreover, the device does not get very warm in idle mode and uses energy economically. In addition, the notebook works at a very low noise level throughout the workload. The two-year warranty is another plus.
On the other hand, the keyboard is a step back compared to earlier models from Lenovo. The screen contrast is too low. Furthermore, the case could be more robust. The frame rates in computer games are also fairly low. The dual graphic system does not manage to produce smooth frame rates for many games.
Overall, the G505s is not really convincing. It offers much less CPU performance than many cheaper Intel powered notebooks, such as the Lenovo G500s or the Wortmann Terra Mobile 1512. At the same time it also does not offer as good an application and game performance as many similarly priced notebooks, such as the Acer Aspire E1-571G. Hence, it is hard to find a reason to buy the G505s.
