Prolonged exposure to warm laptops can cause erythema ab igne (EAI)—also called Toasted Skin Syndrome or Granny’s Tartan—a blotchy, chronic skin condition that is in rare cases associated with some cancers. We do not recommend using any gaming laptop on your lap for long periods of time, as the undersides of all the laptops we tested regularly measured over 43 °C (109 °F) (the threshold for EAI) during even short gaming sessions.

Gaming systems have higher-end components than run-of-the-mill consumer laptops, so their prices will be consequently higher, but the range across the category is huge: from under a grand to $5,000 and up. The best budget gaming laptops start at $800 and can go up to about $1,250. For that, you get a system that can play games at 1,366-by-768 resolution on high graphics quality settings, or at a full HD (1080p) resolution with the details turned down some. Storage may be a hard drive, or a modest-capacity solid-state drive (SSD).
On the AMD side of the fence, the on-chip graphics solutions in the company's A8-, A10-, and A12-series processors are pretty good (as integrated graphics go). As a result, you'll see almost no AMD-based laptops under $1,000 with dedicated graphics. That's because the presence of an AMD CPU, in the first place, is usually a low-price play by the laptop maker. Adding a GPU would just bump up the price.
