Which GPUs to get for deep learning

Is anyone else trying to decide if you should upgrade from 1080 ti's?

I have a box with four of them which have served me well for a while now, and based on just raw performance it looks like upgrading to two RTX 3080s would exceed the performance of my current system.

I'm wondering if I should rush to sell off the cards on the used market before the prices crash and then use that money to swap over to Ampere.

Then, there's also the question of if there will be an RTX 3080 TI which will blow away the RTX 3080 and be a viable card for the next five years like the 1080 TI.

I'm really uncertain about what to do and wonder the calculus other people have done on this decision.

4x 1080Ti are probably about as fast as 2x 3080 if you're able to use FP16. They are most likely faster for FP32. And in any case they provide almost 2x memory.

You also need to account for the 350W rating of the 3080. I think its 100W more than the 1080ti's.
