I don't know though, alienware really catches my attention, besides being 18" I like the design and all... Tough choice, guess I will decide on the better GPU.
That's what makes it tougher. If you look at the benchmark site I posted earlier, the GPUs are really close. When either loses to the other it's only by a few FPS and it's certainly not something you are going to notice. Buy whichever tickles your fancy.
