Last-min deal: Save $167 on AMD’s top-end Ryzen CPU during Prime Day only

A lot of PC parts were on sale for Amazon Prime Big Deals Day, enough that you could probably build a pretty good PC for a lot less than normal. Among the best deals is this one for the AMD Ryzen 9 7900X. It’s a top-tier AMD CPU, and it’s pretty good at everything. You can get it for $382, down from its usual price of $549. That’s a savings of 30%, but act quickly, because Prime Day is almost over.
