I have one of the black macbooks with c2d, a GMA950 graphics card, and 2 gig of ram. When I run Windows XP in Fusion, the fan runs almost constantly - even without any windows applications running (antivirus is running). This bothers me. It's getting time for me to consider a new laptop. Does anyone have any experience with the GeForce 9400M or 9600GT video card laptops? I'm wondering if my experience will be different with either video card.
