While my NVMe Samsung is much faster than my sata Evo, I can't say it is "worth it"
You will see some things go a fair bit faster, other things depend on internet speed, etc.
Of course, if you get one on sale/at a good price, it is easily transferrable to a new build, so that's a thing.
I didn't replace my sata ssd, but trather put OS and most used games/programs on the NVMe drive, with a good chunk of my game library on the sata drive.
Leaving the games that don't load things all the time on the platter.
Makes overall system performance very good.
I would get a 500 Gb one at least, so your most used/ loading heavy things can live on it.
