I like Windows 10. It has the functionality of 7 but the aesthetics of 8. I also really like Edge browser but it's lacking some fundamental features as of now (extensions).
If people are going in-depth about their set-ups I have my nice new PC on my desk alongside my LG 29UB65-P ultrawide monitor, my Sony MDR-1r headphones, a British Army S10 gas mask for some reason (it looks cool), a spot lamp, Novation Launchkey and Launchpad Mini, and Nio 2/4. Oh and a figure of Nemesis and Cerberus. My keyboard is a Corsair K70 and my mouse is Logitech G502.
I built my lovely rig with Slog Bait a couple of months ago.
2x 970 Windforce in SLI and 4790k watercooled and OCed CPU. There are some Portal 2 figures in there as well.
The build was supposed to have a red and black theme but the GPUs had blue LEDs which can't be changed so I just thought "fuck it".
