I have a Geforce GTX 570 and I'm looking to upgrade soon, however until then I would like to slightly overclock my GPU. However it seems that when I overclock it, no matter how little, after a 3-10 minutes in any video game I start to get major stuttering and freezing. After a bit of that my card crashes and recovers, crashing any game I had running. I watched the temperature, it doesn't go over 60 when playing ArmA or Battlefield 4. Let me know if you need any other information thanks.
