Could I get your opinion?

Background: 20 years old. Just got back into playing golf after being away from it for quite awhile. Last summer was my first summer playing a lot like at least 2 times a week. Plan to pay even more then 2 times a week.

I have had my set of clubs for about 5 years. They are worn out and the club heads are pretty dirty, scratched, and scuffed. The grips are starting to peel off but nothing too major. There seems to just be a lot of wear and tear. I am just starting to hit really well with my clubs. The dilemma I have is, should I get a new set of clubs? I am looking at a new set of Tour Edge golf clubs around $300. Is it really worth me getting new clubs?
