Technology in golf equipment has certainly advanced over the past 6 years, but the improvements may not be significant enough to warrant purchasing a new driver if you're happy with the sound and feel of your current one. That being said, getting properly fitted for a driver can help you maximize the performance of your swing and potentially gain more distance or accuracy. A professional fitting can also help you determine if your current driver is the best fit for your swing, and if not, recommend a more suitable one. So, while you may not necessarily need to upgrade your driver, a fitting could certainly be beneficial for improving your consistency and overall performance on the course.
