Any 2Ghz C2D or faster, with a 8600M or higher should run the game well. I played CM on a older notebook, 2.16Ghz C2D, with a ATI X1600 and it played okay, on moderate settings. Just keep this in mind, 8400 or lower is low end, 8600GT is mid-range, 8800s are higher end. Try to get a card with at least 256MB VRAM, although 128MB will be okay, at least with the games out right now. Unless the manufacturer underclocks the video card, it should perform at about the same level as the equivalent desktop models.
