So I have a Acer Aspire AS5750G-6873. It has a GeForce 520m in it. Is it possible to buy just the card of say GeForce 550M and if i could buy just the card. Could I put it in my laptop? And how fast should I go as far as ram. I want to get 2x4gb 1333 laptop ram. Could I replace the i3 in it to an i5? Here is a few links.
