best non nvidia card for 9th gpu?

[poby]

I understand windows won't work with more than 8 gpus of the same brand.  By "Brand" I assume the meaning is either amd or nvidia i.e. you can't use an MSI nvidia card if you have 8 other gigabyte nvidia cards.

That being the case, what is the best AMD based card broadly as good as a GTX 1070 in roughly the same price range?  This is for nicehash.  RX580 seems to be a big step down for mining anything but ether.  I'm looking for something that can be underclocked to use around 120 watts.  Any suggestions?

If you want to stick with Windows. I don't think you have any other option than to go with AMD for the 9th GPU. Tbh, RX 580 works well compared to other AMD counterparts. Vega is good for nicehash but the power consumption is off the roof. It all drops down to two best options for AMD. Either RX580 or Vega.

I think the RX 580 is better as it has lower power consumption and cheaper.

I think if you don't want nVidia cards but only AMD, the best is RX 470.
RX 470 is cheapest than RX 579 and RX580 and has the same hasrate.
And the best for the end : RX 470 use less power than RX 570/RX 580 and RX 480.

RX 470 is only second hand now.
