It's worth it if the games you want to play support it. If you play fast paced competitive games it may not be what you need. However, if you play a lot of games with high end graphics then it's almost a must at this point. The RTX 2060 will probably be your cheapest option but I personally would skip that card. It isn't very powerful when it comes to the RTX features. The 30 series has the second gen tensor cores so you should get some better performance. The 40 series also supports frame interpolation but those cards are crazy expensive. IMO: a 3060 would probably be a good option; but the 30 cards are dropping prices fast. See if you can find a second hand card for cheap.
