I built my own machine with AMD hardware CPU: FX-4350 Black, GPU: R9-2XX, 990 FX chipset and motherboard: ASROCK Extreme 9. OS is Windows 10 Pro, or openSUSE 13.2 Linux on another SSD if necessary - Windows 10 still seems fragile and blue-screens.
I'm beginning development to reach the mobile Android-and-other-Linux-like OS platforms and Windows 10, so I make heavy use of AMD-V in virtualizaton, (e.g. Android, Linux, Windows 10(phone) emulators).
I was using VirtualBox 5.x until it spontaneously hosted 32-bit only environments. So I use Windows 10 Pro's Hyper-V for now.
I prefer the Visual Studio (2015) IDE as of now.
I'm highly interested in using the AMD compute libraries to maximize performance on mobile and desktop platforms built with AMD CPU/GPU/HSA hardware.
