I'm looking for ideas for a PC (non-Mac) laptop that can go to school daily, can do homework that is online-based (meaning Google docs, etc.), and can be a decent gaming machine for Steam-based games. It doesn't really need an optical drive and it should be light enough to carry daily. Probably 14.6-17" screen. The budget needs to be reasonable, but I don't want to be too limiting so I can get a good idea of the options. Thanks in advance for any input and specific models you can recommend.
