This is not a good deal. First of all I highly doubt this mobo and CPU will be Windows 11 compatible so you’re out of luck there. For $373 you can find an AMD Ryzen 5 7600X and mobo combo deal that will vastly outperform this Chinese CPU. Also AMD’s AM5 platform is DDR5 while this Chinese CPU and mobo combo is DDR4. $373 is a ridiculously non competitive price.

CPU + Mobo combo plus a CPU cooler which adds up to about $381.40 which is $8 more than Chinese CPU + mobo combo. I think that’s close enough to be within the margin of price fluctuations. That AM5 mobo comes with four memory slots, PCIe 4.0, USB 3.2 and Wifi 6E. Those features may be worth extra $8 for some.
