So i just got my new PC. It is a Ibuypower Pc with a MSI gtx 760 2gb. IT also has a AMD fx-8320 8-core CPU. I am trying to overclock the GPU to play planetside 2 on ultra settings smoothly. I use MSI afterburner and I slide the GPU overclock to about 150%. I also slide the power limit to the max but for some reason, the max is 115% normal power. Is this because of my 500W PSU or is it because of my graphics card. I have liquid cooling with a ARC high performance cooling fan for heatsink. I also can not change the voltage even if I turn on the option in the options list. I did this overclock once, and then I booted planetside 2 up. It ran stable fr about 30 seconds at 80+ FPS and then it grounded to a halt and my computer crashed.
