Heavy gaming? No. That MX450 is weaker than a GTX1650 mobile and that GPU is already terribly outdated. Maybe if you plan on playing 7 year old games it might be fine.

Things I would consider good enough on a laptop like that. My entire job, MS office, web browsing, document reading and editing, zoom calls, and other basic office tasks. Also some light photo editing and 1080p video editing. As for gaming, I would play any game up to arouns 2010-2015, like Skyrim would run fine, maybe FO4. As for newer games general esports stuff will be fine, Fortnite, Apex, Overwatch, Rocket League, R6S, LoL, that kind of stuff is no problem. CoD and Tarkov probably not on an MX450. With the easier games, you could even dabble in some Twitch streaming with the Intel iGPU’s encoders.

All in all, you’ll have plenty of options. You wont be able to do and play everything. Like CP2077 and Starfield wont run on that. But the list of games and apps that will run is sufficient.
