Couple rumours about price will leave 2080ti owners a bit more optimistic about re-sale value.
I guess that once the new cards come out, if it turns out that people could have held on to their RTX 2080ti's for a few extra months and still sold at around £900, then that is where it kind of did not make sense to sell three months prior to the new released cards, I think it generally makes sense if you have a good backup card to use in the meantime, that way you kind of can live with it.
But when the new cards hit the review sites and if it turns out you can have almost 2080ti gaming for say £649ish + a full warranty, then hmmm it kind of made it worth while....but if it is £499 for 2080ti type power but perhaps with only 8gb of ram, then for me, I would be over the moon.
All ways round, I feel I have edged my bets, my guess, worse case is £900 for 2080ti type gaming card from the new 30X0 range of cards..
