GTX 1070 to RTX 3070?

I think the 3070 drops in Oct. The 3080 dropped last week and it's a ghost, even for some who pre-order. Nvidia claims more are hitting the shelves this week.

The 3090 drops this week and at $1499 retail, 24 GB GDDR6K, two people I know who were dogged last week on the 3080 are ponying up and going worth the 3090 this week instead. They didn't spend the night outside of Microcenter, but went down extremely early (like in the past) and after a few hours were told it wasn't going to happen.
