When it comes to new AMD AM5 motherboards featuring an X670 series chipset, one of the cheapest options right now is the ASRock X670E PG Lightning that retails for around $249 USD. I picked up one of these motherboards at launch and has been working out well on Linux for those wanting to build a cost-minded AMD Zen 4 desktop system.
