After a year of living with the original Nightstalker, I've overhauled everything. The only bits that stayed the same are the motherboard, CPU cooler, and SSD; all other non-peripheral components have been changed, including the case. Therefore, I figured this is essentially a new build.
This machine is my really high-resolution gaming machine and also my multimedia editing rig. My audio equipment is for DAW use for making music.
The Fury X is amazing, handles everything I've thrown at it in 4K, including The Witcher 3 and GTA V, at the maximum refresh rate for HDMI 1.4 - 30 Hz. However, I'm using it at 3200x1800 for gaming since the refresh is a much more fluid 48 Hz. Everything else is done in 4K though. I have a fairly decent overclock on it using Sapphire's TriXX software.
