For starters it's going to be released on console first, and if it's anything like RDR2 and GTA5 both released on pc over a year later, I think GTA5 was year and a half after console release.

Depending on optimization, I'd guess 3060 could run it on lowest everything, turn off everything, 30fps at 1080p and maybe if you're willing 60fps at 720p. This is my guess.

There is another consideration, that it was delayed for so long and developed for consoles that will be over 6 years old lol and the RDNA 2 video chip is comparable to a 3060 ti, so you got that going for you. But you have to factor optimization hence why I'm guessing it'll run like shit on the 3060, but the good news is that it'll run if you're not a graphics mark.
