I'm in Calgary. Different markets, of course.... but $460 seems really high.
I haven't seen a Strix available for a while (similarly, Kijiji), but the last one I saw (probably a couple of weeks to a month ago) was asking less than that.
At this point, I wouldn't get too hung up on it being a Strix card. There's not *that* much headroom in a 1060 anyway.
Almost any 1060 (excluding the mITX single fan cards) for less than the sellers asking for the Strix would likely be a much smarter purchase.
FWIW, ASUS' warranty (supposedly) does not transfer beyond the original purchaser:
ALL ASUS WARRANTY TERMS AND AGREEMENTS ARE NON-TRANSFERABLE AND ONLY APPLY TO THE ORIGINAL UNIT AND ORIGINAL PURCHASER.

So if the card fails on you, you're SOL.
If (I) were to be spending >$450 on a card, I'd really expect a warranty to apply.
While a bit weaker of a card out of the box.... a Gigabyte D5 is $440+Tax ... which is what, 13% for you?

Now, $500 for a 1060 is NOT a good deal, by any stretch. But at least you'd have a 3 year warranty for the extra $20-$30 paid vs the Strix you're considering.
If you're buying a used 1060.... personally, I wouldn't look to pay much beyond about $300 CDN, regardless of the model -- easier said than done though if you NEED a GPU.
