I decided to overclock my CPU and GPU (graphics card) to squeeze out as much performance as I could. The best thing to do is to do a Google search and find others who have attempted overclocking the same hardware that you have. Getting it wrong can be very expensive.

If you want to get an decent gains you will need to invest in some better cooling. I went for a simple, self-contained water CPU cooler. My GPU already has 3 fans but my biggest issue there was there is these fans are right next to my case which can get very, very hot.
I tried using the BIOS’ automatic overclocking but it has never resulted in a stable PC. Having found a good article on overclocking the same hardware I started making adjustments and then testing them by playing Battlefield4. Often everything appears stable until trying to play it.
Testing this way is terribly inefficient and frustrating. So I searched for some tools that would stress out my system in a more controlled way. Both of these tools are free.
