So I just bought a gtx 1070 used for my brothers pc to upgrade a older gpu but everytime he plays for around 30minutes the game crashes, when he played warzone 2 it crashed and then popped up with the crash report, but everything ran fine with the older gpu which is gtx 770 2gb and I ran msi kombuster and heaven test until they finished benchmarking it looked fine, had like 70c-80c temp
