So far, my experience with the GTX 960 has been great, no problems. I just have a question, im overclocking the core clock by +180(MSI Afterburner) because at +200 I see graphical artifacts, question is am I fine running at +180 core clock MHz? my max temp on The Witcher 3 (the main game I overclock for,) is 64 degrees celcius while overclocking, is that good? do I have to worry about my gpu burning out? Thanks.
