So I'm going to university in September and I need a laptop> I really don't trust laptops that are pre made from like dell etc because they always end up becoming extremely slow but if any of you have any suggestions on good pre made laptops I can always look at them too. I'm looking for a site to build a laptop like they will build it for you. I really need it for just university stuff as I'm doing computer science so I'll need a fast laptop and that crash easily and my budget is around 700 - 800 pounds and won't need an operating system as I'll install it myself since I use windows 7.
