The 8 GB RAM in this model runs at 4,267 MHz It Is NOT Expandable
The 12 GB RAM in the 15.6" model runs at 3,200 MHz (4 GB + 8 GB)
PLUS the EVO platform is designed to be more responsive.
These will play many games, but the refresh rate of 60 FPS and lacking a Dedicated Graphics Module
means they aren't True "Gamer", but they do have plenty of speed and responsiveness for multitasking.
It's only $$$, BUT an EVO i7 w/16 GB RAM would be tops.
