Hello All, I currently have the laptop listen in my profile: Dell XPS 15 L502X, I5, 4GB, GT540M I'm looking to upgrade but I'm not sure if it will be worth the extra cost? I use it for browsing, watching high res films, streaming football matches, connecting hdmi to tv. I like the 13inch screen and decent speakers. Better battery would be nice. I'm quite happy with my current laptop but to invest money in a new one I'd like to see a big improvement in speed/performance. Would I be better off just sticking another 4gb of ram in it or investing in another laptop? Budget would be anything from £300 to maybe £800 if it was jaw droppingly good. I've looked at the new dell xps13, asus ux305 but they dont seem to be that much of a step up. Please can someone guide me with this?
