The laptop which you posted here is okay for most game developers, but depends on what you are going to use to make games.
You really need to choose a computer base on:
1) The system needed to run your software and programs for game development. Look at minimum requirements as such by the developers of the software and applications.
2) Consider a computer which is similar to your target end users.
I use Toshiba and Lenova laptops which are slightly more powerful than yours and I have no problems.
