Resistor/Capacitor broke off, anyone knows if it matters?

So, I had some issues with installing the GPU in the case, and the GPU bottom (those metals things at the bottom) ended up scratching part of the motherboard. From what I can tell, there's a bunch of similar components all the way up, so I'd think there's redundancy, so I guess it's not that important. Here is a picture:

PC boots fine into bios, fans work, stuff are recognized, mouse and keyboard also works, but I haven't really done much beyond that.

Motherboard is: MSI B650 Gaming Plus Wifi

It's located here, and on them, it is written K72 then vertically smaller K2 (the 2 has an underline):

Should I get a new motherboard?

Edit: Better quality image, and new image host added.

I could be wrong, but it looks like the part that came off is in the fenced off area for onboard audio, so it might be ok if you're using audio from the HDMI on the GPU.
- Audio from jack appears... to be working fine. Obviously I am just going by ears and some songs playing, so I can't tell if some minor frequency or noise is present.
  
  There's 6 audio ports on the back of the motherboard (which is why it looks like there are extra/redundant parts) and it could be any of them, not just the main stereo (green) output. But if your main audio is working fine, it should be usable.
Looks like a mosfet got broken. I am no electro-ologist, but it is probably going to have weird voltages wherever that mosfet serves. Might be okay for a while or maybe not.

If I wanted to save the board, I’d order a replacement from Digikey or elsewhere. Just ID one next to it and order it up. Have a finer tip on the soldering iron and Bob’s your uncle!
- I first read that as "finger tip" and was wondering why you were telling OP to burn themselves
  
  Something something equivalent exchange, user must suffer the way the board suffered, karma and all that
- Looks like maybe the copper pad came off for one of the contacts.
  
  In that case a resolder might be a pain, and require some extra work to expose more of the trace.
I don't know enough about motherboards to really say for sure, and hopefully someone more knowledgeable can come in to correct anything, but I'd be concerned if that chipped off piece happens to be part of the voltage regulator module. My call is to play it safe with electronics, because worst case scenario is that it could fry other components or catch on fire
