Gaming desktop PCs are tower systems built around a dedicated graphics card, with the cooling and power delivery needed to sustain high frame rates over long sessions. This category covers Acer Predator, Lenovo Legion and ASUS models, from mainstream builds for 1080p play up to enthusiast towers with GeForce RTX 5080 graphics, Core Ultra 9 processors and 64GB DDR5.
The graphics card sets the resolution and frame rate you can realistically target, so match it to your monitor first and adjust CPU, memory and storage around it. Tower chassis also leave room for later GPU or storage upgrades, unlike compact systems.
