Kingdom Come Deliverance is the most notable example of this. The monastery mission is absolutely brutal both by how difficult it's intended to be, and by how broke it is, on a technical level.

It's definitely interesting, but it's so difficult.

I would try to go for a used 6800XT, I snatched one at 320€ some months ago, it should be easy to find now for 300€. If you want performance for your money, and you use Linux, that would be my way to go.
