Can i run bf 4 or arma 3 on my laptop

[xdwonder911]

Hello I'm thinking of buying an Asus NoteBook F751LN for 650€
(CPU: Intel Core i5–4210U, 1.7 GHz (3M Cache, up to 2.7 GHz),
RAM: 6 GB DDR3,
GPU: Nvidia Geforce GT840 3 GB DDR3).
So my question is, will i be able to run bf 4 and arma 3, since gta V is probably out of the question, right ?

Battlefield 4 should be playable but the laptop will struggle to play arma 3 as it is a cpu intense game. It could play gta 5 but may struggle as the cpu is ok. I would upgrade the ram to 8 if this is possible as this is the min for most games.
