It was $499 this morning and when I refreshed the page this afternoon it became $399.
From memory it was around $650 from pbtech when they last had stock.
The closest comparable price I can find is i9-10850K on Amazon US for $350USD($585NZD)+GST+Shipping
Slower 5800X alternative, without PCI 4. Not worth it even at this price unless you need to use Intel (or you really really like the Avengers).
