looking at spending around 1k - 1.5k on a laptop in a few months, i've always used a desktop but need a bit more mobility these days. The ideal laptop i guess i would be looking at would be something that will last me around 6 years, is very quiet and doesn't overheat, screen size doesn't matter as i can plug it into my monitor when upstairs, any recommendations? performance is important i hate waiting for things to load. the only thing ill be playing it on will be football manager.
