Modern PC hardware has reached a point where performance isn’t a concern on most machines. As long as you have a new 6-core processor and a $350–$400 GPU, you can easily power through 1440p gaming. Many users focus instead on reducing the power consumption and, consequently, operating temperatures. Tweaking your BIOS/UEFI is a fantastic way to cut down on power usage without affecting performance too much. You just need to ensure you’re fully aware of the effects of disabling or enabling a setting.
