Consult on server configuration for password cracking. Thank you all!

[haohaohao]

I have many 2007 versions of EXCEL documents that need to be cracked, so I'm planning to configure a password cracking server. Would you like to know if the following server configuration is reasonable? Do you have any better configuration suggestions? Thank you all!
cpu:Xeon e5-2665 X 2
Memory: recc ddr3 1600 32G
Graphics:nvidia 1080TI x4
Hard disk:SSD 250G

Thank you all!

Office 2007 is very slow. Four GPUs likely won't get you very far, especially if you have a lot of documents.

Are there any good solutions?

Sure -- a lot more GPUs.
