Laptops are not for games, but if you must play on one, get one with beefy gpu, it matters more than cpu, something like intel 4400 would run it on medium settings without shadows i think
If a gaming laptop with dual 780m / 880m / or even 980m's are not for gaming then what are they for? I have a desktop with a 980 SC and a laptop with dual 880m's. My laptop out performs my desktop in many cases.
This whole laptops can't game is just an ignorant statement as it is not the core 2 era anymore. Technology has advanced but peoples knowledge on the matter has not.
