Hi, I am an engineering student that does no gaming and I am in the market for a new laptop and have some options im sort of confused about the differences. one has 1 gig dual channel and core duo 2300 1.66 ghz 2mb cache the other is just a pentium m 1.73 with 1gb shared ram the runs at slow fsb (??). I was wondering if the first would be overkill for what I am doing (no gaming, general applications, some big engr applications), the difference is about 400 dollars in the two, what would you guys suggest, thanks
