I just realized that the biggest problem to incorporate Acorn into existing rigs is this:
"At launch, Acorn will work exclusivity with SQRL Miner. We'll provide an SDK and API documentation later this Fall for other miners to integrate Acorn support." I am not sure how this miner is going to to work with various pools or NiceHash, for instance.
Also, the longer I look at options the more confused I am getting about how Acorn (any model) is going to improve my ethash mining for GTX1080Ti with ETHlargement pill (53.5 MHs).
Could I please, get advice on this? Simply put, I am mostly interested in Ether mining with high end GPUs
It isnt. It is not going to help you in a profitable way (other than maybe operating costs). You are looking for the wrong solution.
Saying it again - the same thing I said in the first post. ETH is supported but not the target. You will not see the 30 MH gain potential on ETH in the majority of cases. You can see it on Lyra2Rev2, X16r, and other algorithms where 30MH is a lot more.
