Asking for my gaming "ammunition"?

[deadseventeen]

Hello everyone,
I need a little help which one I should upgrade for gaming.

This is my laptop specs:
ASUS S451LB
Windows 8 Ent 64 bit
RAM 4GB
Processor Intel(R) Core i3-4010U CPU @1.70 GHz
Graphics :

Intel(R) HD Graphics Family (1765 MB approx. total memory)

NVidia GeForce GT 740M (3781 MB for available graphics memory)

So, I planned to upgrade one between my graphics card and RAM, could you suggest for me which one?
Btw, I've searched and still doubt if I choose graphics card because I don't know which type.

Will be glad if you could help. Thanks!

With laptops, generally the only thing you can do is add more RAM. Its possible the existing GPU could be soldered in place, or a custom size that wont allow you to put any old graphics card in its place. Furthermore, a different GPU could lead to heat issues or use to much power.

You can't put a graphics card in a laptop, graphics cards are for desktop PCs, laptops use chips instead which are not replaceable.
Your laptop is also very weak, you're looking at a new rig.
