RTX 1660 Super MSRP  $229
RTX 3060 MSRP  $329
I definitely wouldn't buy an RTX 1660 Super over $250 now. Might be worth considering buying a used GPU if the price is interesting.
And $500 for an RTX 3060 is also expensive today.

And $500 for an RTX 3060 is also expensive today.

The current price on feeBay in the U.S. for a used RTX 3060 is $430, while new ones are $450. That probably means you can buy them wholesale for $400. This isn't very far from the MSRP after considering the 8% inflation over the past year. I don't really think that price will go down further unless something happens to ETH.
