it's a laptop ...for gaming .......ok you can use if for that, but gaming on such a small display is not what i would like to do , and if it has to be a x11 then the bottom right one with the i7 , as for games you need processing and graphics power as much as you can get
sure most games will work on the x11 with i3 too just dont expect wonders in the fps department even on low settings
sorry just my opinion ...gaming on laptops , you have to be really desperate for a game to play it on a laptop while you cant access your gaming rig for example
alienware has much better offerings the
Area 51 ALX Desktop for example to really enjoy gaming without worrys about settings , just put in the game and start playing , even the aurora series will make mince meat out of the x11
and if they are to pricey then hmm build your own gaming rig and you will see what you get for less
just want to make sure you dont come back after you bought the x11 and complain "i only get 20 fps out of it while playing game xx what can i do?"
