HP pavilion has i3 core 4th generation windows 8.1 which is upgradable to windows 10. Which is very good . The design of the laptop is excellent . It has 4 gb of ram , 500 gb od hard disk with graphic card also. The worst part of this laptop comes when u r going to do cyber security and software testing. The hardware part of this laptop is not at all good.
If you want to do the cyber security and the software testing then dont buy this laptop at all otherwise it is good . The lag is there while playing high enf games. The youtube videos also lag when it comes to 720p and also at 1080p .
