pascal looks more of an upgrade than the 980ti in all fairness.
I assumed with the build being 13 months old that they'd be much to upgrade with plenty of gains , by the looks, a better cooling should be worth while and then the option of O/c is there if I need to squeeze out any forced perfoamnce betwen now andn next November ( thats the upgrade window I tend to have)
I also assume by Novemeber they'll be better i7's or whatever is next
So maybe the itch can be left for a few months ?
