Which graphics card for Minecraft without shaders and Fortnite?

Which graphics card would you recommend for MC and Fortnite so that I can play both smoothly?

My processor: Ryzen 5 2600

Power supply: be quiet! System Power 9 400 watts

RAM: Since I have to assemble the PC first, I still don't know whether I should use 12GB or 16GB…

At best, the graphics card should cost less than 100 euro, but I would also be willing to pay a price up to a maximum of 140 euro.

First: definitely take 16Gb ram. Especially for Minecraft. And then I would choose a used 1060 6Gb

Either used or rx570 8gb. A used 1060 6gb seems to me a good idea or maybe a used gtx 1050ti

1050 ti is enough!
