Hey I am not sure if this topic is right but my question is, is it worth to make 2 accounts like 1 for only gaming 1 game and internet like facebook/youtube and other for rest small games movies and etc downloads.
Not really. It is usually recommended to make a separate administrator account and normal (restricted) user account, though. With this arrangement you'd do nearly everything (game/surf) on the user account and only log in as admin to install software / change system settings.
