Hello folks!

I just found out that my PC from 2018 with its GTX 1080 is infact capable of an SLI upgrade. Now Needless to say thats a terrible Idea! Being well aware of that, I still wanna do it if not for no other reason then for Fun!

So I wanted to ask what are some pitfalls I should look out for here? Some things I should be aware of when taking on this frankly Silly Idea? Thanks!
