Hi, I'm wanting to update my graphics card in my laptop (An Inspiron N5110), which currently has both an integrated graphics card and a Nvidia GeForce 525M graphics card. I want to know if it is possible to replace the Nvidia with a better graphics card for gaming in my laptop (I believe it is, but I would like to be certain before I spend any money) and if this is possible, any advice on which <£100 graphics card would be best for gaming. Many thanks
