tbh, the big retailers like Best Buy usually drop their stock in waves on Tuesday mornings around 10 AM EST, but you gotta be careful with the current supply chain volatility. Honestly, idk if I'd rush into the first available listing you see on Amazon Marketplace—there’s been a ton of reports about poor packaging leading to PCB flex during shipping, and you really dont want to deal with an RMA on a high-end card right out of the gate. Before you jump on the next drop, are you aiming for the AMD reference model or are you holding out for a specific AIB partner card? Personally, I'd wait for the partner cards with more robust power stages and VRM cooling, especially since these chips can have some intense transient spikes that'll trip older PSUs. Just make sure your buying from "Sold and Shipped by" the actual retailer so your manufacturer warranty is actually valid if you run into any silicon lottery issues or coil whine.
