my laptop is a toshiba satellite 18.4 inch widescreen, full HD, bluray burner, 4gb ram (could have got more, but ram is cheaper to buy separately, same with harddrive), exactly like the qosmio yet more customizable. at the time of purchase i researched everywhere i could find that slkd configurable laptops, if its pre-configured, they either charge too much or rip you off somewhere. i even get a 25% discount at dell, and i couldnt make a better deal than i got with my laptop. This is a year ago though. but it plays any pc game currently available on highest settings with no lag at all.
but based on budget, an d without looking at others suggestions, ill add to be sure to configure your own laptop. its like buying from walmart or best buy, if its pre configured, they either screw you over on the processor or graphics card (the most expensive components of the computer) or they charge more than its worth.
like i said above, whatever you get if you dont mind waiting a bit longer, you can save money buy going with graphics card and processor from company, and get the smallest HDD and ram they offer and buy those elsewhere, they are easy to replace and saves some money buy upgrading yourself. I also prefer Intel over AMD, but you will always get people that root for one or the either. Intel is more expensive of course, but like i said depends on budget. I run AMD in my desktop and Intel in my laptop.
