Could you comment on the quality of the output files too? I recently moved from an AMD card to a 1080Ti and I find the output files from ShadowPlay very difficult to work with (audio sync issues) and they're often corrupt, to a point where I don't even bother using it anymore.
Glad to hear you got it sorted out. I also ordered the XFX one from Amazon and glad to report it's not noisy, very glad as it's much more of a pain returning from another country!
