That will depend on what kind of games, although someone could recommend the "best gaming laptop for under $1500." Oh, is that 1500 USD?
For some games a 900 dollar laptop will do the job. For a few, 3,000 wouldn't cut it. Depends on the games. So a little more information would help. Also, if you are going to be carrying it around, max weight? What do you consider to be "disappointing battery life?"
