Cheapest deal I've seen. Understood this is comparable to a GTX 1060 6gb.

For those who prefers a slightly different (RED) look and a backplate, the MKII card comes in at $17 ($339.15 ebay+ / $354.15 non-ebay+) more. I think these have a slightly different dimensions but everything else is the same.

As an alternative, they are selling a few nVidia 1060 3GB for $280 with eBay Plus, only marginally slower than RX580, but costs $42 less
