I imagine the vast majority of people are having no problems, but yeah, some definitely are having driver problems since it's basically new technology. But some games saw a 10-15% fps improvement in some games with just the latest driver so I'm curious as to how good it can get. With that being said, look at the GPU forum right here. Plenty of Nvidia users are having driver issues too.
I'm waiting till Black Friday to get mine, if there's a good offer on the Red Devil or Sapphire Nitro+ (or 2070S if it's a decent model under £450).
