Only if they can be used to the fullest extend.
At this time, very few (if any) WUs fully load a 3090, 3080, or a 2080 Ti even...
I think for folding and deep learning the low end 4000 series of GPUs will be excellent, just because I expect them to perform higher, while using even less power!
At this performance levels, the costprice isn't the biggest concern.
It's how many you can run, before tripping a breaker?

Science dictates how many atoms need to be simulated. There's a loose relationship between atom count and shader count. GPUs with too many shaders become inefficient because the fahcore can't increase the parallelism of small proteins.

But there are plans to work around this, like running two (or more) trajectories at once on a big GPU ...

... and who knows - researchers are clever people - as the availability/capability of gpus that can run models with far more atoms increases there is a fair chance that projects will be created that actually push these ... for the RTX30 series there are now a number that fully utilise these - assignment challenges still remain but with a bit of luck (and a lot of hard work behind the scenes) that may get improved.
