Overpowered laptops are near useless. They usually weigh 15-20lbs, have the battery life of power plant run by AAs, and get so hot they will literally melt through plastic surfaces.
If it's not actually useful or portable, there's absolutely zero reason to spend 2-3x the money on one over a desktop that has the same specs.
