Amazon have some 3950 at $750 bucks right now
AMD Ryzen 9 3950X 16-core, 32-thread Unlocked Desktop Processor, without Cooler https://www.amazon.com/dp/B07ZTYKLZW/ref=cm_sw_r_cp_api_i_RG.dEbNY29MWB
I see in some Spanish forums that after week 35 of production the overclock potencial increase in some batch of this Ryzen 9 processors versus processors batch before 35 week . It is true how I can identify the week of production of my new 3900x.
