which best port if m using 6x vega rigs? 4448 or 4450? Thankyou
In the grand scheme of things, it doesn't matter. You will make the same amount of Ombre if you mine long enough.
However,
I believe 4450 would be the better choice because of the higher Difficulty. If your cards cannot manage it, try 4448, but they should be able to handle 4450.
