I recently purchased one of the new Macbooks. One aspect of this which I haven't seen a lot of people talk about is how it does in real world scenarios for us gamers. I installed Windows XP on the machine and installed some game demos for the newest games out as well as some I have which are within a year old. After doing some testing I've been quite surprised with how well the video card handles everything. I'm not going to sit here and post benchmarks and framerates (thats what the professional reviewers are for), but I wanted to see what other people thought. I installed the new Tomb Raider Underworld Demo. I was expecting the video card to choke quickly, but to my surprise it handled everything really well. I ran the game at full settings and 2XX Anti-aliasing in the Macbook's native resolution. I did notice from frame rate drop when I played a scene that involved me floating in water, but it wasn't the to the point of being unplayable. Considering this is a brand new game with bleeding edge effects I think the shared video card proved quite capable.
