If you do something that's very sensitive to CPU/GPU speed such as media encoding then every little helps as it means more transcodes and/or less time to do them meaning more private time for you, your family and so forth.
Getting a system spot on stable 100% when overclocking can take time, knowledge and patience unless you have an unlocked CPU multiplier which simplifies things immensely (far less settings to worry about). As for GPU, most ship at frequencies already close to their maximums so overclocking them doesn't bring much in the form of performance.
