All of those laptops are rubbish (almost any laptop under $800 is) and none of them will game worth a damn but if I had to pick one I'd go with the second.
Sorry, I wasn't that clear. By gaming I meant little bit of Warcraft III here and there. I am not planning on playing insane game like GTA 4 or Battle Field 3. Heavy gaming will come after I graduate [2 years from now]; probably build my own rig by than.
Since you chose the second link, how do you think i'll do in converting videos? And thanks for the feedback though, greatly appreciated.
