I built this computer over Christmas as a replacement for my extremely under powered dual core laptop. I primarily use this build for my software development, but I also play a wide variety of video games on it. This computer can run multiple games at once with full graphics and 60+ FPS. The CPU temperature averages at around 55 degrees Fahrenheit (up to 90 when under load), and the GPU core averages at 80 degrees. When under load, the GPU can be up to around 110 degrees, but turning the fan controls up to high can usually take it back down below 100. I expect this computer to perform well for at least five years due to the powerful processor, good cooling system, and the non-fragmenting nature of the solid state drives.
