Cheap computers at Best Buy that can run Minecraft with at least 40 fps?

I was looking at the asus Rog g750jm, but its really expensive. I'm looking at the macbook air, but its still pretty expensive. My price range is $0-800.

Check on Craigslist. You can oftentimes buy used laptops that have okay specs, but are practically worthless (as all used computers are).

Pro computer tip-macs are for business, not for gaming, and I'd suggest a laptop, it is cheap, portable, and all in one.

Nothing at best buy is cheap…
