I would like to buy a good configuration laptop. With 1/2GB ram, intel duo core processor and 2ghz… Suggest me a good model at a good price. what season is it best to buy a laptop? Is it thanksgiving/christmas? or now?? (school offers are running now)

I know that doesnt hurt PC’s that much since they have much larger, powerful, and more efficient cooling systems. But since laptops are smaller and their parts are more miniaturized, I would think they would be weaker. I have a Dell XPS M1530. On average I will have my laptop on for about a 5-8 hour stretch, then it will be off until the next day when I do it again.
