You could buy HP 15-ab031TX or Asus X555LJ-XX041H. Both laptops are great and can run gta v in low-med settings easily. Keep in mind that the first laptop has 4 gb of Nvidia Geforce 920m as opposed to what amazon says. You could check the first comment to verify.
The second laptop is equally great but has GT 920m.GTX 920m doesnt exist.
These both laptops can run gta v and any other game easily. I would recommend you to buy the first one as its reviews are great.If you have any problem with ram,you could always upgrade it as one ram slot is unused.
