Which laptop to buy from Trading perspective?

This question might sound silly but may actually be relevant for some. I have been investing in the markets in CFDs etc but new to day trading and scalping. Learning the ropes sincerely. My old laptop is on deathbed so am planning to buy a nice new, premium one shortly ($1500++). Wonder if there are any features I should look out for in a laptop which traders love to use. Or a laptop itself that's great from trading perspective.
