Hey, I'm a newbie when it comes to computer hardware etc so please take it easy on me. I'm looking into upgrading my current graphics card in my laptop. Now before everybody says it's impossible, just humor me please and tell me the details no matter how hard it is. I have a Dell XPS 15 L521x i5-3230m 2.6 ghz with 8gb ram and a Nvidia Geforce Gt 630m. and i want to upgrade the graphics card to maybe something like a gt 650m or if there's one better. Also how difficult is it to replace the cpu with a better one? I know it's possible to upgrade the components on some laptops, I am just curious if my laptop has the compatibility to be upgraded. Thanks!
