I use my pc mainly for gaming as well as school work. No problems at all so far (have used only 2 days through) gpu and cpu idle at 37 C* . The PC is also relatively quiet. I haven't overclocked anything and do not plan to. I did would have used a 980ti but I had already purchased the titan x just 1 week before it came out. The system runs anything on ultra and I have yet to hear the fans go up for any reason.
