I am using this dell inspiron 5558 laptop from 4-5 months. There is no doubt by saying its a beast device. It is very easy to use. It has 15.6 full hd display which is crystal clear and very vivid . The keyboard and touchpad are very comfortable to use . Specification of the laptop is : intel i5 5th gen , 8gb ram , nvidia 920m 4gb graphic card , which can handle any task from editing to gaming. I play game like Gta V , Witcher and there is no issue while playing heavy games. There is not any heating issues . Battery backup is also good.
So you can go for this laptop.
