My friend has this laptop and I used it for several time. It has core i3 4th gen processor and 4 gb ram but many high end games are lagging. and when I try to multitasking, the laptop start lagging too much. Hard disk getting 100% very quickly if I open 2-3 apps related to hard disk. good laptop for normal use, even it has 4 gb ram and 500 gb hard disk.
