My brother has a ryzen 1600 we can updateUnless you can guarantee the bios is up to date, none of them. If you can, the x370 GT3.
Take A320 right out of consideration, it's not up to snuff power wise for 8 cores, 3 cores tops. You also may be better off with a good b450 motherboard, not only that it's compatible right out of the box but also better with fast RAM.in my country only have these 3 options on promotion, which one should I choose?

*** Biostar X370 GT3 $113

Wrong button,. 4 cores but every one with even 2600 makes problems. 2700 is 65W TDP while under load it can pull 100W+ of electrical power. Those two things are related but not same.There is no such thing as a 3 core ryzen. A320 can run a 2700, but cannot overclock. They are really made for business rigs. The R7 2700 is only a 65w chip.
For Ryzen CPUs TDP is typically very close to max power consumption. Anandtech has the 2700 drawing ~62W under load. https://www.anandtech.com/show/12625/amd-second-generation-ryzen-7-2700x-2700-ryzen-5-2600x-2600/8Wrong button,. 4 cores but every one with even 2600 makes problems. 2700 is 65W TDP while under load it can pull 100W+ of electrical power.
