Hi there,
I have the following problem. Everytime i try to play a Game like Witcher III or GTA V. It begins to stutter after like 10 minutes. I have 60 FPS and then it drops and thats where the Screena nd Sound start to stutter. What component does cause this issue? and how to fix it?

My Specs are:
CPU: i5- 3570k overclocked at 4.0 GHZ
GPU: MSI RX 480
MB: Z77 Extreme3
PSU: 630 W Bequiet Bronze
RAM: 8GB Ram

If you need more specs, jsut tell me.
I hope someone can help me.
Thank you in advance
