I'm buying a gaming computer, is this good more minecraft and that's really it?

Looking at the specs of the laptop you can max out some of the modern games with fair fps minecraft no problem of running it on those specs max out{ ultra settings }

This is way overkill for Minecraft. But yes Minecraft will run on it too. You really don't need much of a computer to run Minecraft.

Depends how good you want Minecraft to perform and look.

This computer will run 2015 Games on Ultra Settings and you worrying about Minecraft?
