I use this computer for gaming. It performs rather well, and the only issues I have had with it are occasional crashes when launching a game in Windows 10 (which I shortly downgraded after). However, I think this was due to a problem with one of the monitors, and not any of the hardware in the tower. It plays most games on mid graphics, and could probably play higher graphics with another stick of RAM. You'll also notice that the Power Supply is an Insignia, but I couldn't find the part on the list, so I picked one that was very similar to what I have in my machine.
