Running on an Asus G60JX that I've had for a little over 2 years now. Cost me $900 when I bought it.

Core i5 @2.27GHz (Hyper-threaded dual core)
NVidia GTS 360M @ 1GB GDDR5 VRAM
4GB DDR3 RAM

Running at these settings with a near constant 25+ in Ul'dah, 30+ in Grid/Limsa, 40+ in fields and 50+ in dungeons/buildings/primals



They no longer make this laptop, but any of the current Asus Republic of Gamers laptops should do you very well, especially compared to 2 year old hardware. Don't buy that overpriced Alienware crap.
