RTX 3080 TI - blocking mining vs matrix multiplication

I want to buy RTX 3080 TI for computing only (AI - mainly matrix multiplication). Is it ok choice?
I read that 3080 TI is blocking eg. mining etherium - if i want to use it for matrix multiplication is it matter? Maybe i should buy another one like RTX 3080 (without TI) or 3090?
I’m going to use it very hard for about one year continuously (experiment of AI).
Thantks a lot for answeres.
Best regards
