Ryzen 5000 CPUs are going to get quite valuable in a week... AMD ZA funding is depleted, meaning that prices will be about as follows from late next:
5600X R 6,300
5800X R 9,000
5900X R 10,800
5950X R 15,800
If you have one that you're selling, wait a week. If you want to buy one, get one before you get nailed with much higher pricing.
At those prices, importing through amazon becomes appealing with potential warranty shenanigans be damned.
