Questions about switching to NVIDIA (sorry for my english)

Is it worth switching from a 7900 XT to a 5070 Ti right now?

I’ve been testing AMD for over a year now, but I’m extremely dissatisfied with the card and the driver stability.

I’m asking because the 5070 Ti is almost as expensive as a 5080, which brings me to my second question: should I switch to a 5070 Ti or a 5080?

Are we currently in a good time to buy, or should I wait a bit longer?
