Hello wanted to ask a question, Performance 4GB ram to 8gb of ram you notice when you're playing? improves the graphics? how much goes to spend the money on more and 8gb ram 256gb version. Or is it better to buy the 4GB version and buy a 480GB msata and replace? msata 480GB costs about 200 € (I'm from Spain sorry for my English lol) I await your answers, and thank you very much.
