You need to understand that is not the right question.
here is my previous post on this subject: https://bitcointalk.org/index.php?topic=1306983.msg59904434#msg59904434
or in summary: "you need 2724 2080ti approximately to do puzzle 64 in one month with bitcrack. 1362 if you correctly guess which half of the range it is in.
or in other words 1,830,035 optimal 2080ti hours for $24,000. mine is a founder edition and can hit 1,400,000,000 Mk/s with -b 4532 -t 32 -p 584."

running One 2080ti 24/7 is not really advisable.
running 2724 is not worth $24,000.

a 3070 might be similar to my 2080ti and according to some data I have ~954 3090s would do it in a month.

so to wrap it up
1. you have to first guess a lucky number and hope it's close.
2. get as efficient (modern NVIDIA for cuda) a card as you can
3. stick with it for months
...just for the slim chance of getting it.

some 'attempts' have been made at pooling resources but stick with it for months still applies
