I want to buy a new gaming laptop. I'm not a whiz with computers, but from what I understand asus, lenovo, toshiba, and samsung are all decent gaming machines. The $700 price point could go a little either way. I also would consider a used/refurbished rig. Minimum 15.6" screen size, don't really care about battery life as it will be plugged in most of the time. I understand I need a dedicated graphics card, and I would like to play most new games on high/maxed out graphics settings. Any help would be appreciated. Thanks!
