If you want a gaming laptop i suggest it has windows 7 an ssd and 8-16 gb of RAM 8 is perfect 16 if just overkill but is needed if you do alot of rendering and a good gpu
alienwares are good because they offer all of that good stuff but ofcourse at a high ass price
and the ones this guy posted are nice but have windows 8 and dont have and SSD
issue with windows 8 is i see alot of complaints with games and applications on that OS than you do with 7
and a SSD will let you boot up games and your OS much faster.
so pretty much
Windows 7
8-16 GB RAM
SSD with 300+GB for games and OS
and a GPU 870m+ is preferred due to it will handle newer games and will have to upgrade much later
