With the dramatic increase in DDR5 memory prices many folks wanting to upgrade to the AMD5 format are deciding to stick with their AMD4 motherboard and just upgrade their CPU. I upgraded recently and have this used processor available. I used it for flight simulation which is very CPU intensive and it performed very well. Lots of gaming benchmarks online.

When released it was over $500, now $375 new, used on eBay with a US seller, $175-$275. So this is a good deal and you’re buying local which has certain advantages.

The AMD Ryzen 9 5900X is a powerful 12-core, 24-thread desktop CPU from the Zen 3 architecture, featuring a 3.7 GHz base clock, up to 4.8 GHz boost, 64MB L3 cache, and a 105W TDP, designed for high-performance gaming and creator tasks, requiring a discrete GPU and using the AM4 socket with PCIe 4.0 support, but comes without a cooler.
