I am not a gamer but I am pretty sure the reason for overclocking is for gaming. Is there any other benefits to it? Please use your own words when explaining this.
Yup, the main reason for overclocking is for increased gaming performance. Another big reason is for bragging rights, "I can overclock mine higher than yours".
Overclocking does have benefits for regular use. Apps will open quicker, videos play smoother, etc.
