I bought my current set of clubs (new) for 100$. I keep hearing this repeated that it's not the clubs that make a good golfer it's the swing. I don't intend to buy another set of clubs until my current set breaks apart or I get much much better.

I am wondering though, if I had a set of 1000$ or even 5000$ custom-fitted clubs would that have any real effect on my distance? I don't mean an 10 extra yards, I'm thinking in terms of another 40 or 50 yards. That's what I mean by effect.
