Will see how much my 4070 Ti loses when I sell it. I will again look at what 3080 Ti's would have sold for when that happens and I will see how much extra I lost. Don't think there will be much in it.
It depends on how much you bought it for which is what matters really. Quite a few new 4070 Ti's have been £499 now, guess they are clearing stock still, but then the there have been may 4070 Supers for under £500 as well on good deal days, with cards being ~£529-540 on a bad day.
Someone was asking for advice if they should get a 4080 Super now with a view to moving to 5000 series, based on a £950 buy price, but I said unless you are keeping it for a long time don't bother, as the 4070 Super is the best deal as they'll lose £200 max, where as the 4080 Super is going to end up losing £400 or more with out a shadow of a doubt. Impossible thing to guess is the actual release date.
