What components should I get?

[Wooderson]

Sorry, I mean't 6 cores :S

Also, to me the Phenom X4 II was cheaper than the Bulldozer one you recommended... Unless i've made a stupid error in my calculation (i'm crap at maths so that might be the case)

I know that RuneScape doesn't take much of a computer to run very smoothly, but my laptops graphics card (Intergrated Intel Mobile 4 series) is pretty useless when it comes to FPS.

I use the downloadable client from Jagex to run the game, which i would think is better than using a browser.

I don't plan on playing any other games other than RS, Amnesia and Penumbra so yeah.... No worries.

As I mentioned before, I want to be able to record the games without having massive lag which I have on this laptop at the moment.

Thanks for all the replies
