MSRP is largely irrelevant.
Few are going to buy them at that, and with the 3070Ti FE knocking on the door of £500-600 going by what we know, the next move is likely to remove the 3080 FE cards altogether, avoiding the cost comparison entirely.
Right now, unless you are one of the fortunate few, a 3060ti is £800+, and 3070 is a £1000 card. In this climate, a £1200 3080 fits.
The danger for us as consumers is that Nvidia are moving to normalize these prices, so that after the supply issues are fixed, which is not likely until the 40 series cards appear, if then, a supposed entry level 4060 could be a £500 card.
At that point, its sensible to just switch to console for gaming.
