Will upgrading my RAM improve pc game performance?

It's more to do with your GPU, it's quite outdated. Not to mention your processor. Plus, it's a laptop.

Only really high end laptops can run BF3 at a decent rate.

That makes no sense its either a AMD with a Radeon graphics card or a shitty intel with intel sucky dedicated graphics.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
