5080 or new 4090 (similar price, both new)

Just seen a marketplace ad for a new 4090 (that has just been sitting in the box unused apparently) for $2500aud. 5080 FE retails for $2000aud, but as Australia doesn’t get FE cards, I’m not expecting to be able to get a card on launch for less than ~$2400.

Does this seem worthwhile?
