I build this gaming computer for my brother so that he could play his Steam games and League Of Legends without lag. The graphics card was okay at first, but started to artifact after about two months. I sent it back to Gigabyte to be repaired, but they returned it to me, saying that nothing was wrong. It still has intermittent artifacts. It comes and goes. Heat isn't an issue -- I've stress tested it and temperatures remained under 80 C. Another problem is that the motherboard did not have a USB 3.0 header for the front USB ports, so those are inoperative until the adapter cable arrives from Shenzhen. This was not my first computer build.
