I built this system around 3 years ago and it's been rock solid eversince. I upgraded couple components during this time (I used to have a 980). I swapped the sound system, switched couple fans (because the ones that came with the case were making too much noise) and so on.
It's an overclocked system so the CPU is running at 4.5Ghz at 1.4v and GPU is clocked to 2050Mhz. CPU temp is below 80 degrees (c) on full load (because the case is more focused on sound dampening instead of airflow) and GPU doesn't exceed 75 degrees even when I'm gaming on VR or 4K.
