Question Does anyone have this particular 980TI? I just bought one still sealed.

Why is everyone so obsessed with overclocking these days when the actual benefits from it are negligible in terms of fps? Yay, i've gained 5 more fps!
Experimentation, feeling of accomplishment, the need to have everything on your system min maxed, curiosity, out of options like buying new gpu due to the prices, boredom... That's just what came to mind while writing it.

Don't search a reason, it's the decision of the owner. Present to them facts about overclocking and leave them be.
