I've been using Nvidia graphics in my gaming PCs for quite a while -- at least a couple of generations. Short dalliances with water-cooled monsters like AMD's R9 295X2 and R9 Fury X haven't been enough to tear me away. Maybe it's time to change, though; after some time away from AMD cards, I gave MSI's R9 390X Gaming 8GB GPU a bit of a test drive, and came away impressed.
