Years ago, I built my mother in law a computer. It had windows XP on it. Every weirdo and their kid who visited her would download another bit of malware/toolbars/whatever, and about once a month I would have to fix it. So I put Ubuntu on it, and it literally never had a problem again. I’d use Mint now, but if you’re doing some basic games and web browsing, Linux is fine. I game with my pc, which uses Linux Mint, and the only issue I had was getting the Nvidia graphics card working. It wasn’t really hard for someone who builds computers but it might be difficult for a “normal” user.
