You think the MBP gets ridiculously hot, ha, wait until you see what you have in store with the AlienWare. I had previously owned one. Yes, insanely fast, but over 11 lbs and the fans (blaring loud) shot out heat towards my the hand holding my mouse which would get so hot I would have to take breaks, not a convenient thing when gaming (the sole reason I went with the AW). I learnt my lesson, use a real desktop for gaming and forget about the whole idea of a "gaming laptop". You really get the worst of both worlds. And please don't tell me you're doing multi-media and require 2 nVidia 260M in SLi. My 15 MBP does everything just fine. I keep my gaming elsewhere. But good luck with OS X on the system.
