RE: Club3D Radeon R9 280 royalKing, can my pc handle it

Hi Gerrit03,
Overclocking can damage your components so there is always a risk of damaging your components. It is your decision if it is ok to damage your components.
I suggest you to read a bit about your mainboard and cpu specifications in order to determine how far you can push your system as well as understanding a bit the basics of overlocking. This will help you to achieve your desired results. 
If your decision is to go for overclocking, make sure you always do it in small increments, this is safe but longer in the process to get your final results.
Make sure you test your system before any overclock is done. This will provide you a start up point which you can compare later on how far you have gone with your project.
Cheers
