laptops are more portable but for gaming they have heat issues as there so small there no airflow.to game on a laptop with a gaming card some people need to use cooling mats to keep the laptop for over heating. now laptop is the 500 price range have soilder on video chipsets most times intel or stock amd chipset. with laptops if you drop it a short hight..kill the drive in it. i also seen as a tech broken off power ports from people tripping on laptop power cord. desktop use standard over the shelf parts...easy to upgrade. better cooler so there better gaming units.
