I built this system as a replacement for my 6 year old AMD2 6000+/8800GTX system.
I am using it for 4k Gaming, 3d/4k movies, 4k video editing, and high-res Photo editing.
The PC is getting great frame rates at 4k with GTA on max settings (AA off), same with Witcher 3 and Batman Arkham Knight.
The Nepton 240m liquid CPU cooler was an extremely tight fit in this case. I wouldn't recommend this setup with the same case/mobo combo unless you are ready to play a very hard game of tetris. However, now that it's assembled and working I am very happy with it.
This PC connected to a 55" Samsung SUHD 4k 3d TV. I'm very happy with the display.
The CPU is overclocked by 1.2ghz stable to 4.5ghz.
I have not yet overclocked the GPU (or needed to)
