Improvements and actualizations
To improve performance of the CPU without replacing it and without changing other parts of the computer, we can think about better cooling and overclocking. If we want to change the CPU, it can be way easier if we have chosen a good motherboard earlier. In general OverDriving packages are not recommended. It is strongly recommended to wait for at least second release of the new generation of processors, as the first ones are usually not working too well.
