Dang, even the lowest one on eBay completed transaction (ignore the returned untested one), it's still $430 CAD shipped. So that's about a new Arc B580 price but it got 4GB advantage over the B580. But the B580 is only as good as a 3060Ti it seems. Looking at old GN review, it's somewhat on par with 3080Ti and 3080. Looking at FBM Vancouver, 3080 is at low as $425 but that is only 10GB. A new 9060XT 16GB is $550 before tax.
Since it looks like ROCM 7 still support RDNA 2 so I think $380 local (matching eBay) and $430 shipped sounds fair. It may be slower than the 3080 for AI work but that extra VRAM helps with bigger models. 9060XT would be closer to $600 with tax.
