Can you buy a 3090Ti for mining or 3090? I heard the difference in performance is not big, the information I found online says 135MH on 3090ti even if you can get this card for MSRP is it worth it since 3090 is very close in performance too.
I preferred to bet on 3080 Ti which is for me the best ratio for future crypto-like Ergo, RVN and more
All Nvidia high-end GPUs are good for other algorithms like Flux, Ergo and RVN including RTX3070ti and RTX3080, OP trying to choose between 3090 and 3090ti is not worth it because there is only a 15-20MH difference, go for the cheapest.
