Sli/Crossfire on Asus Maximus VI Impact?

So i was just pondering the idea of multi gpu config on my impact.

it has an M.2 slot on it: https://www.asus.com/us/Motherboards/MAXIMUS_VI_IMPACT/

If i got these would it work?

gee, so much complication... yeah it'll work but you'll get performance x2 or x1 is it really worth it?

its one of thoes things that i could do just because. it would be a cool experiment, and if it works i can brag about crossfire on my mini ITX board. i dont think SLI will work because i think it had a 8x requirement for some reason.

you could do crossfire just fine... but .... i'd also recommend longer extension cable.

Alright. Thanks. Now I need to figure out how to mount this in my bitfenix prodigy if i do it.... I might replace the top fans....

i recommend getting a stand for it.

here are some good pics/ideas for it. I myself use something similar to person on that forum called retrominer
