Sorry for a bit late reply.
I did some small research on this.
And there are a few questions (regarding the laptop I stated in first post).
1. The laptop has a 'non-removable battery' (4-cell), so I am concerned if I buy it, in future I will or will not be able to change the battery.
2. Is the NVIDIA 750m 4GB DDR3 'okay-ish' for games like Mad-Max, MGS : PP, FIFA 16, BF : Hardline, Just Cause 3, and a few more.
I have checked out some Gameplay videos on YouTube with this card and games like GTA V, FC 4, BF 4, and few others worked fune on medium settings or medium- high mixed settings.
But, still I a bit confused.
3. Intel I7 4500u Haswell 1.8 GHz Dual Core (Turbo Boost upto 3.0 GHz), is it enough to handle heavy games and other apps and stuff ?
4. I have read some reviews about the laptop thatit heats quite a bit while playing games on it.
That's all I remember right now.
Waiting for some replies.
