Is the extra 16GB of RAM worth it?

Probably, but only if you actually use more than 16GB. The price jump from 16GB to 32GB is only about $25–30, which is cheap for DDR4 at the end of its life. For gaming, 16GB is still enough; for heavy multitasking, virtual machines, or video editing, 32GB makes a real difference. Check your usage—if you’re consistently over 80%, spring for 32GB.
