>>105754582 (OP)16GB is still fine for general use.
Emails, web browsing, streaming video, some light productivity software and light casual gaming.
32GB should be the minimum standard for any purpose-built gaming PC or a computer that will be doing more than generic emails/web browsing.
Personally I've got 2x16GB and have had since 2015, but my next platform upgrade I'll grab 2x32GB
