A 1660 SUPER is generally shown to perform within a few percent or so of a 1660 Ti, so that might also be worth considering if you can find one at a significantly lower price.
Of course, the 1660 Ti has been out for almost two years already, and a new generation of graphics cards has already started coming out at the higher-end. The 3060 is expected to be announced next month (though I would expect a $300+ MSRP), and there may be 3050-class cards announced soon too, so it might not be the best time to buy a graphics card in this price range, unless you were to really need one right away.
