2020 and 2021 has so far been an absolute disaster when it comes to getting hold of new graphics cards, especially from Nvidia. You need a lot of luck and patience to be able to grab a card or a lot of money to buy it via Ebay.

One way to get hold of a RTX Series 30-card is to buy it in a laptop. Earlier this year Nvidia released the mobile version of the RTX 30 Series and these of course are a bit easier to get hold of as you buy them together with a laptop.
