What computer is good for gaming?

I suggest ASUS, but what you need is an ASUS that's for windows 7, Because I've heard that people who get windows 8.1 and 10 have all kinds of problems with it.

So good luck!

Alienware and asus are really good for gaming.

As long as it's a PC, just about anything you find will run minecraft just fine.

Make one yourself. Pick custom parts. You can blow any prebuilt computer out of the water if you build one yourself by picking custom parts. But you need to learn a bit about computers and thats just too much to post here
