Adding 16 GB to that should be cheap if you have four slots. I would recommend doing that along with an upgrade to a 2 TB m2 ssd. You can just clone your old drive to your new drive using clonezilla to fix the partition size.

I did exactly this upgrade a few months ago. I did it so I could stop worrying about running out of storage. Don't expect much performance improvement from the ram and ssd upgrade, though.

For a significant performance upgrade you can get a ryzen 5 5800 or 5800 x3d for a little more. That's the cpu I went with and I've been very happy with it.

Make those upgrades first, then decide if you want to look at upgrading the graphics card. What you have should keep up just fine for now, though, assuming you're not trying to max out unoptomized games.

Not bad. Not much to add to that unless you’re using heavy memory virtualized servers, etc.
