2020 M1 Macbook Pro for $650?

I've been using an HP Envy 15t-ep100 for a little over 3 years now and I'm thinking about switching to a Macbook because the Envy is getting too heavy to carry around (almost 5lbs without the charger) and I can't get more than 2-3 hours out of it without having it plugged in.

This is also going to be my first Mac but I'm honestly not sure what I should be looking for (Should I get something older intel or brand new?). I'm a nursing student so I only do typical productivity work and I play games occasionally so I might keep the Envy as a gaming machine.

These are the specs but I don't know if that's a good deal:

• M1 8-core and 8-core GPU
• 16GB RAM
• 512GB SSD

What do you guys think? Thank you!
