In a statement to PC Gamer, EVGA say (perhaps a bit non-specifically) that "Yes, all failed 3090’s are being replaced." According to PC Gamer, "there is reportedly also now a specific 'New World' category when it comes to giving the reason for the return of the faulty graphics card.".
In a video testing New World with an RTX 3090 GPU, Jay says that an EVGA member told him players with affected GPUs are "already getting their replacement cards," saying that shipping has already begun for replacements.
EVGA's RTX 3090 cards appeared to be the most mentioned failures from players, though other series cards and models reportedly experienced overheating
Amazon's latest update on the issue says "We have implemented an update to reduce GPU load in menu screens by clamping FPS - this does not affect settings in game world available via the Settings/Video menu."
