In that case, it probably makes a lot of sense to wait for the 3060. It will be significantly cheaper than ANY of those cards you've mentioned, and is supposed to have like ~80% of the performance of the 2080 and right now a 2060 Super is more than sufficient for Ultra 1080p gaming and is passable for 1440p gaming, so something more than that should easily be capable of handling either of those acceptable, maybe even admirably well.
I don't see much point in buying two year old technology when latest gen parts are already here, are going to be cheaper once they become readily available and are going to become readily available over the next month or two most likely.
