I've been reading over the forums and it looks like I'm going with the updated white macbook over the alum macbook (need the firewire). My question, what can you really expect out of the Nvdia 9400m? I'm putting 4gigs of Ram in mine. I'm a huge fan of Blizzard and cannot wait for Starcraft 2. I hope this thing could handle it. Anyone have any theories or experience using the macbook for gaming?
