I think the 4070 Ti Super is the best of these for those on a looser budget and in reality it's just a lower-end version of a 4080, same die as well, for the price that everyone wanted the 4080 to launch at. I think those who want the most punch for best value and haven't already updraged to a 40 series card should be on the lookout for it and I can't wait to see the reviews for it.
I like the 4080 Super but in comparison to a 4090 it doesn't impress me as much for the price. If you're coming from a 3070 or less and don't want to spend all the extra cash for even an MSRP 4090, if you could find one, then the 4080 Super is an okay choice and at least has a little more improvement over the original. Nothing wrong with the 4070 Super either but the one in the middle is the standout, imho. However, if on a really tight budget then the 4070 isn't the worst value either. I say this after experiencing close to the same with the mobile 4080 in my laptop which uses a similar die. You can do a lot with this card at 1440p.
What I'm ultimately wondering about is availability with any of these since those d***n scalpers are still making nuisances of themselves.
