Been shopping around for a new laptop to replace my old one. Basically I'm looking for a laptop that is for school, programming and of course, gaming

The laptop's gotta a large harddrive, wireless networking, don't care if it has OS or not, capable of dual booting (most laptop should be able to right?)
The reason I'm asking you guys to pick it out for me is that I haven' been keeping up with the latest tech shit going on, especially laptops.
