Overclocking your GPU gives you a limited increase in performance, it is better you leave the base clock alone for headroom for performance increases

Understanding What Overclocking a GPU Does

Before we get into the overclocking process, let’s first talk about what overclocking a GPU actually does.

Called the base clock, different cards usually have the potential to surpass the speed set by the manufacturer. Essentially, overclocking a GPU increases its performance by boosting the speed that the graphical processor works at.

By overclocking the speed, your GPU will increase in temperature and it will draw more power. It’s important to find a good balance between more performance and a stable temperature for your graphics card.

Every GPU is different. For example, your GTX 1080 may be able to safely overclock to a higher speed than your friend’s GTX 1080. As a result, you must test your own overclocking speeds to find the sweet spot.

If you try to push your GPU too hard with the MSI Afterburner overclocking software, your graphics card will either show graphical glitches, or your PC will crash.

Don’t worry – you can simply dial your GPU speeds back down to a safe level if this happens. It’s best to start slow and make your way up until you notice problems.

From my research it is better to leave your baseclock alone, as you need the headroom for performance increases. It is the same for Windows performance starts degrading once the harddisk is full, no amount of virtual memory you increase will make any difference, once your harddish is full your performance will start degrading. Windows need at least a spare space of 2GB for I/O to work properly.
