Convinced, I am getting it too.RTX 2080 here, so I think I'll be okay .
As for waiting - no chance for me. Thankfully, it seems almost all the bugs are visual/glitches, and nothing gamebreaking seems to be reported, so I think I can stomach that. Besides, Fallout: New Vegas was a glitchy mess on release, yet it was still one of the most enjoyable RPG experiences for me.
I also don't want to risk getting inadvertently spoiled.
In GOG obviously. No need to give to Valve 30% of the money.
