I am going to start college this fall and i was looking around for a new laptop. While i am looking it seems like some manufactures advertise optimus with their gpu's and other do not. I was just wondering if it comes standard or if i should look for it specifically. I would like to get a laptop that has it so that i can have a decent battery life (for going to classes) but to later play games (things like skyrim but not crysis or anything). Any help would be much appreciated. If you need more specifics just ask.
