Hi, I have a GTX 980 MSI GAMING TWIN FROZR. When I first overclocked I decided against it cause I manged to get to +225 on the core (1490mhz) and 1516 mhz boost but it was at 1560 something in valley. I was wondering what would be considered a safe overclock with no over volting and will still make the card last 2 years. (I will probably end up getting a new graphics card when it comes out but just in case I don't) Currently I have it on 110% Power at 110+ core thanks for the help guys in advance!
