well, the situation right now is quite nonsense to buy a rtx because of the ridiculous high price from the scalpers. why buy a usd 3000 card when the normal price is just usd 599 (rtx 3080)? so buy a gtx 1660 is quite reasonable. maybe gtx 3050 is a wise choice considered it's the cheapest card from 3xxx series
btw, gtx 1050ti eventhough is slow still be able to render. i already tested it in my old pc and it get the jobs done.
