IMO, neither new clubs, shafts, nor balls will correct your problem. Take notice of your post title: Hitting the driver.... The ultimate challenge for golfers is to control the normal, mental desire to hit the ball. We, the ordinary golfers of the world, must learn to swing the club effectively which means using the hips to generate the power needed to swing the clubhead at a predictable 100mph. Trying the 'hit the ball', a typical upper body motion, is as effective as pushing on a rope. Wish you success.
May i recommend an old book, 'Learning Golf' by Percy Boomer. Not full of tips but loaded with a complete understanding of the nuances and difficulties of learning how to swing the club, which is what we must learn to do. If you did not learn golf as a youth, the learning game is uphill all the way.
Swinging the club is golf's first challenge. The second is learning to accept the failure, then move to the next shot.
