Which of these motherboard should i buy?

[Valeny]

Hi guys , i'm building my first "gamer" pc, pretty budget, i am noob in hardware subject.
For the moment, this is the pc: CPU: AMD Ryzen 3 3200g + Radeon Vega 8 RAM: 2x8 3200 MHz HDD 1 TB. I have to choose the mother now and i am between these (don't recommend other than one of these, i get this in my country because of warranty, budget and all of that):
- Gigabyte B350M-DS3H V2: https://www.gigabyte.com/Motherboard/GA-AB350M-DS3H-V2-rev-11#kf
- GIGABYTE GA-AX370M DS3H: https://www.gigabyte.com/Motherboard/GA-AX370M-DS3H-rev-1x#kf
- Gigabyte B450M DS3H HDMI RGB Ready M.2 NVMe: https://www.gigabyte.com/Motherboard/B450M-DS3H-rev-10#kf
I know i could be ok even with a A320 with my current setup but if in the future i want to Overclock, upgrade to Ryzen 5/7 or similar, put a dedicated VGA, more RAM, SSD or things like these, i prefer to pay a bit more now and be prepared for that situation.
As i see there isn't a big difference in usb, m.2, Ram ports and that stuff, pretty the same. (4 RAM slots each, i think)
My two biggest concerns are:

• What about the OC? I was told the x370 OC is better than B450. Is that right? How much better? Is worth it? What about the 350 OC?
• I want to upgrade it as late as i can. The B450 would be the better in that case for being the newest?

Should i be worried about BIOS? As far as i know, the store can update the BIOS for any CPU and ready to go. Isn't it? The 350 has nothing to do against the x370 and B450? (So many questions haha sorry)
That's all, thanks for reading.

The problem is those motherboards may need a BIOS update to boot a Ryzen 3000 series CPU. For OOTB compatibility with Ryzen 3000 it should be X570, B450 Plus or Max, or have the "Ryzen 3000 Ready" sticker.

The AX370 appears to be Ryzen 3000 Ready, but I don't see the B450 Ready sticker.

I think the store where i gonna buy it, will update the BIOS for me, i guess that shouldn't be problem. How about the other specs?

b450 or higher and something with decent vrm heat sinks if you want to try and oc.

They are essentially the same motherboard, down to the number of internal I/O connectors and external ports. The B450 is just a newer revision.

Spec Comparison

Some would say the X370 has better/more VRMs, but looking at the photos the B450 has 7 VRMs, and the X370 only has 6.

Both are from the "DS3H" lineup which is the budget segment (Gaming and Aorus are the midrange/premium segment). Save your money and go with the B450.
