doom3 is a totally new experience on the lappie, eh? I had a GF4 desktop which barely made the cut for minimum settings. the detail is just amazing to me, it's a totally new experience. I'd DEFINATLEY suggest hooking up your laptop to 4 speakers. i about crapped my pants when i heard stuff behind me when playing. maybe that's lame, but just reinforces my appreciation for this chuck of hardware.
