I'm using a Sager 15" laptop with a GTX670M GPU and it runs the current engine on high settings, but I bumped everything down to Standard with the exception of certain AA options which I left a little higher so I get 60FPS evrywhere and not just when there are no people around. The laptop I have right now can be purchased for under $1K from ExoticPC (I think?) with the exception of a few items I added like a BluRay drive and a different screen. Personally if I could have waited I would have for the 675M or 680M to come out since they have about a 30-40% improvement over the 670M but I haven't found a game yet that the laptop won't run at an acceptable level.
Besides I still have my main gaming rig if I want to run stuff at max settings, the laptop was more for a long period of time I just spent without the above said gaming rig due to a move and when I travel for work.
