I'll have to agree with the previous poster in reference to 17" laptops being a semi-portable desktop replacement. Most 17" gaming laptops are going to be heavier and provide less than steller battery life. Most of these machines will be "permaplug" so to speak. However there are mobile GPU/ graphix cards that will allow you to play on high settings. I have an asus G72 gaming laptop and I play WoW and DaO on high with AA maxed on both. It has a 1GB GeForce GTX 260M. I would recommend looking into the Asus G series of laptops because they are made for gaming.
