Lenovo G-580 powered by Intel, is a good laptop. This laptop is quite rough and tough. The laptop specifications are 15.6” display with build in camera and speakers. It also comes with build in DVD-RW. The laptop comes with many unique feature such as smart fan, one key rescue system and many more.
