Should I buy 16GB or 32GB of RAM for a new PC?

Go with 32GB. The price gap between 16GB and 32GB is shrinking fast—typically just $30 to $60 more for the same speed and latency. Games, browsers, and even Slack are memory hogs now, so 16GB is the new minimum, not the sweet spot. Future you will thank you when you don’t have to close Chrome tabs to run a game. Only save the money if you literally only check email and watch YouTube.
