Best laptop money can buy to you is one you make yourself. I simply cant remember the site but basicly you decide the "shell" and interior for it and you can get it much cheaper than alienware ones, you can upgrade it when you like and if something brokes down you can fix it yourself.
Its some US place so you must pay some tax from there to EU, but its still so cheap in comparison to current EU prices that its worth of it.
Will find out what that place is when I get back home and have my own comp to use. Just remember with 99.99% of laptops what you pay for is complete crap inside for price of more than what actual parts costs. You get all kind of crap programs added by those companies and they actually slow comp down, in comparison to getting it in either parts or assembled for you with just raw windows installed.
Without a really good knowledge of the physical aspects of computing I'd avoid this completely tbh. Laptops are extremely difficult to build from scratch - it is an entirely different ball game to building a base.
Buy one made
You talk based on knownledge or based on "I feel" stuff? Cause they are very same to build, problem is you cant open and fix stuff because those firms building laptops are taking shortcuts and saving money and using bad stuff while doing so. Also very often you lose your warranty if you open em. But they are same computers and same parts inside of em, they are as easy to build as normal comp if in a way not even easier. I have opened a lot of em and fixed stuff and basics are very same, so please dont come here to post your stuff when you honestly dont know smeg! You only spook people to pay for something they wouldnt need to. If you have ever built computer you can build laptop simple as that.
Nitrous:
Yet I suggest to get your laptop from some dealer which builds it for you based on what you want (I mean some company that makes them without name not with name like alienware or so, but they buy their barebones of these big dealers and build you the comp you want on parts you want)... like you can decide barebone system for it (example you want asus modelxxx or dell modelxxx barebone for it, then processor, GPU, HD etc... That way you get exactly what you want and dont want. Also they usually dont install any of those crap that all dells, asus etc. do to their laptops. It is win win deal for both sides, as sometimes looking parts for laptops can be bit hellish operation at least in Finland.
Laptops built such way are called DIY laptops/notebooks those are "best" and easiest way to get exactly what you want for the price you can afford, without being tied to compromises of big companies.
I know that at least OCZ allows you to decide all major parts for your system and they will even put it up for you, making it exactly what you want... More of a question is whatta hell you need laptop for?
You see your problem in here is that you want moveable thing that isnt really moveable... It simply is impossible scenario... I can get you laptop that runs crysis on full (or any other high resourses needed game), yet whan you pull the plug and carry it to class it runs 1.5 hours and dies in Word page. Whats the point of having such then? If you want good laptop and game with it or so it must have big screen... 15" is moveable 17" not really 19 and up well they weight and their size is way too big to be really moveable... so whats the point?
How much good does it give you to spend 1.8k pounds to something that you really cant use all over? What you actually do need is either one of those new AMD systems where you can have separate 2nd GPU which you keep home and which allows some speed when needed with separate power source, yet being useable without one for normal stuff...
Or well you could start to be smart and get normal table comp for like 800 pounds (really really good one) and one of those mini laptops with like 10" moitor and good keyb and 8hours of battery in full use. Thats only way to get best of both sides, not only make compromises between speed and battery life.
I mean who of us doesnt want to get comp that can run any modern games with any speed and then just put it in case and carry it with us to school to do some school work and play some games between classes... but when it starts to weight a ton and its dimensions are huge, it produces more heat than average hairdryer and cant run on battery for more than hour no matter what you do, and when it gets old or breaks down you cant do anything to it yourself, what is the point of its "mobility" anymore?
