XTX was a bloodbath and sold out instantly, presumably to scalpers.
The inferior XT is all that's left. ~5% lower price for 15% less performance, wouldn't recommend anyone pick up one.
It is, however, around 30% faster than a 6950XT. You decide, OZRRP.
Alternatives - appear to be reference boards

Personally, I'll wait for & prefer the AIB versions (ideally better acoustic performance / lower coil whine)
-Edit2- looks like they're all gone
Great bang for buck compared to 4080.
Bummer about the 7900XTX
