Thank you for the very thorough review Steve - it must have been a ton of work (and one you most certainly didn't enjoy).
I know I will be monikered public enemy nr1 after this, but I think this GPU is not that bad IN THE CURRENT MARKET. There is nothing at 200$ point, or even it the vicinity. Nothing. Is it fair? Hell no. But that's where we are. And one can game with this card (though preferably on PCIE 4.0).
My biggest grief is the x4 PCI-E limitation, I can't imagine it brings so much savings that it makes it worthwile. The 64-bit memory bus is a bummer too, but think the bandwidth is enough (just, by the skin of it teeth...) for the GPU anyway.
But, if someone needs something to game on, and has a PCI-E 4.0 motherboard, this card can be a lifesaver (there, I said it. Let the stones fly at me...). I'm sorry but the cost per frame analysis is completely off this world (talking about the ebay one here: the MSRP is a theoretical value, like my ideal waist size: once it was true, for a very short while, and will never return). But seriously: 1650 for 170$? Where? It is more than twice of that here, IN POUNDS. 330$ for a 3060? Really? Sign me right up, I will take that immediately (it is more like 6-700 quids).
The only thing remotely reflecting reality is the price of a used RX570. Still off, but not by multipliers, just percentage. Sorry Steve, but in the current market, if that card is selling for 200$, that would provide excellent price/performance ratio. I don't say this is how it should be (and I cherish my little 1070 Jetstream), but the market is what it is. For a 4.0 motherboard owner, this is a viable opttion.
