The weirdest corrupted video on an NVidia card
This is the kind of thing that makes you think, this really only happens to me.
Back in June, when the availability and price of graphics card finally approached relatively normal values, I got myself an new ASUS GeForce TUF Gaming RTX 3070 Ti OC Edition (to replace the old ASUS GeForce GTX 1070 STRIX from 2017). It still was still nearly $800 but it was clearly never going to come down to $570 the old one costed back in August 2017.
Then, in September, the new card died. Somewhat surreptitiously...
