Dell's base warranty is 1 year in many countries. At the same time, as many private reviews on the forums have shown, for avid players, failures of video chips and power piping begin in about 1.5-2 years. Which is clearly burdensome for a normal person earning money by work.
I always recommend that hardcore gamers buy Dell's 3 year on-site warranty where possible (and actually works by speed of repair and replacement). This is just beneficial, because the probability of their laptops failing after 2 years is maximum with sustained high load. Dell, for this very reason, keeps clearly inflated prices (in recent years) in order to control financial risks in warranty cases.
Any "gaming" laptops are extremely unreliable under heavy loads. They are effective (by time of use) only as a working tool with a below-average load. And if you choose the quietest models in the profile for maximum performance. As once there was a very quiet G5 5587 with a huge weight and a body from a 17" laptop.
