Question a320 for gaming

It'll work but don't expect exceptional boost frequencies. A320 boards usually have subpar VRM cooling and power delivery. Ryzen 5 is fine but I wouldn't put a Ryzen 7 or above on that, so be mindful.
 
If it has the needed bios update, yes it will work. You may, or may not hit as high of boost frequencies, as you would on a better equipped board, with better power delivery though. What is your system budget?
i'm actually still saving. i know i could just wait and save more, but i need a pc soon. and my budget now for a motherboard is around $65-70. or can you recommend a good board at that price range?
