AMD's re-released Ryzen 7 5800X3D sold out almost immediately when it launched, and since then, we've seen scalpers circle the chip and demand double the MSRP (or more). Hopefully, we'll get more in stock, but if you're tired of waiting, you can easily upgrade to a DDR5 platform with these Prime Day CPUs deals, all of which are cheaper than the 5800X3D's recommended $350 MSRP.

The idea is that if you can save money on your CPU, you'll have more money to spend on DDR5. And although the total platform cost rises above that $350 mark, you also make out with a much better processor, as well as DDR5 memory that you can use for future upgrades.Based on our daily RAM price tracking, you can expect to spend around $150 to $200 on a 16GB kit of DDR5 memory right now, while 32GB kits sit around $400. We recommend 32GB for most systems, but 16GB will get you by in the meantime. With some of these CPUs, the discount completely eliminates the cost of buying DDR5, in fact.

The Ryzen 7 5800X3D is currently in stock on Amazon for MSRP. However, it's on back order, with estimated ship times in the second half of July. Given that time frame, that's when we expect a larger restock of the chip across retailers.
