in my experience it's the budget graphics ( not gaming) options that manufacturers quickly drop support for.
I bought a used a laptop with a basic AMD CPU and separate graphics chip and there was no working win 10 driver for it. the generic microsoft one kept crashing. I had to revert the device to windows 7 to make it workable. as it was a laptop, swapping out the graphics was not a practical option.
that 1660Ti will push to to buy a newer , bigger PSU probably. I also have the 1050ti single fan ITX mini card, in a DELL PC . A 1660Ti will not fit my case, or my wallet
