I recently purchased a dell xps 15. It comes with 2.66 ghz, superclocked to 3.2. It also includes a Nvidia geforce 420M 1 GB and 6 gb ddr. Will this rig be able to handle new games at high detail settings for the next several years, at least?
Depending on the design, some laptops might experience overheating. But unless you don't keep the cooling system clean, I don't think your laptop will get damaged. Like Abstract Hero mentioned, I too test my machine to the limit and I haven't had any damage due to heating ( and my laptop is an acer aspire that's 6 years old - on which starcraft 2 run very well at low settings btw hehe )
I think cleaning laptops cooling systems is extremely overlooked. Actually for the common user I think cleaning any cooling system desktop or laptop goes overlooked.
