This is a laptop and not really a gaming laptop. It would be able to run Minecraft and 5 nights at freddies, not sure of performance with the garrys mod. Minecraft will run ok on it but 5 nights at freddies you might have occasional freeze framing.
http://www.tomshardware.com/answers/id-2357954/intel-core-4000m-amd-6410.htmlFor a gaming system, I suggest a desktop computer unless a desktop doesnt make sense for your needs. To have a good gaming laptop your going to be forking out a good amount of money. Desktop gaming systems are the cheaper way to go because even with an average CPU, you can add a decent video card and still come out with more money left in your pocket than a laptop that matches in performance. Additionally a desktop computer allows a path of upgrade without having to replace the entire computer when it no longer can play modern titles or titles that have been patched with updates to textures etc that become more demanding. An example of a game that becomes more modern that increases in resource needs would be a game like World of Warcraft that when it initially came out could run on a Pentium III 800Mhz CPU with a decent 64MB video card, but of which now in 2014 ( 10 years later ) the minimum specs is a dual-core CPU and video card with at least 512MB video RAM, and 5 years ago the minimum was a Pentium 4 or Pentium D and a video card at 256MB video RAM.
If this laptop was bought, it might play the games now, but because its not a gaming laptop a future game update or new game title of interest might not run well on it.
I own both portable and desktop computers and use my portable computers rarely for gaming and desktops purely for gaming. The laptop or netbook I use for everything else but serious gaming. They might run Facebook games and Minecraft ok, but they are not really gaming systems.
