AMD GPUs vs. nVidia GPUs for Dolphin

[Silent Gunner]

I was about to go and sell my current video card for an upgrade, and I was wondering if Dolphin would be negatively affected by using, say, an R9 380 as opposed to a GTX 960. The reason I ask is that I have heard that PCSX2 does not work well with AMD video cards in OpenGL mode. (which is really bad since some games need a feature in said emulator's OpenGL mode to avoid graphical glitches) Considering the fact that I play regular PC games as well and not just emulators, I was wondering just how badly emulators may be affected by an AMD GPU as opposed to an nVidia one.
