I sold my 3080FE to CeX, dropped it off on Sunday and got the payment notice today, can`t complain as I got £1190 which paid for my 3080ti FE and have some change too.
Would have been much better off by just finding the extra cash and going for the full fat 3090 experience.
Now you have the hot running runt of the litter
Tempted to do the same myself wiht my 3080 but I don't have any way to bypass the 1 card per household limit. 3090's always hang around long enough to snag anyway.
