Basically 4.2TF is the minimum and 8.4TF is the maximum. However, to get 8.4 you will need to make sacrifices in various departments that require heavy coding.
I see indies getting more out of it or less graphic heavy games or maybe games that don't require much physics such as destruction.
A game like Destiny that has pretty much static assets and zero destruction might be able to draw on more performance.
