I sorta get the future proofing argument. I built a machine in 2014 with a 970gtx and it still holds up today, if i had the 980, it'd be another year or two before I actually noticed performance hits rather than hitting limitations right now.

In that 8 years, I also went from dual 1080 monitors to dual 1440 monitors. Who knows if one of these monitors would die in the next 8-10 years and I opt for some 4k monitors because the price came way down.

There's nothing I hate more than buying computers, so if I can shell out a little extra money now for a couple extra years of not thinking about my computer, I'm gonna do it.
