Don't plan on gamming on a laptop unless you have like 3000 dollars to spend on one. If it is just for regular use i would say an athlon XP 2500+ or around there would be a decent choice. Don't go for the celeron because they have very little onboard cache memory and this will slow down your computer a lot. I would say any XP processor would be nice with about 512-1024 ram and about a 60 gig hdd at either 5400rpm or if you can 7200rpm is better.
