What is going to be the best laptop for my needs?

I want a laptop that will be able to have a fine connection with the internet, I dont need the best gaming computer because i only play this really old game, and i want the computer to have a crisp clear screen and i have looked at a lot of laptops and i think the best laptop would be one with a big screen and great portability. those are some of my basic needs so can you help me find a good laptop for around 500-600?
