True.
Cant understand why neither of them is available but thats Life.
As divine said 1060 is fine as well, 1660 even better and costs around 30€ more.
Whatever choice you make, just dont take a card with 3 GB of Memory...take 6 GB (or even 8 depending on Card).
As long as u take a Card from the GTX 1xxx or RTX 2xxx Series with at least 6 GB of Ram you will be fine!
