Definitely for you to decide, but if you’re on a desktop in a single family home you’re probably fine. A laptop that you bring around with you I would highly advise against. I would probably also evaluate what other functions the computer serves. Just gaming or also do you do your job on that machine. What else does that machine have access to?
I have one. No dead pixels. It doesn’t necessarily do fancy things but that’s sort of why I got it. $30 and it tells the time, shows me notifications and lasts over a week before I have to charge it. Eeeeevery now and then I’ll use it to control media or play 2048. Hey it even counts my steps!
