Watch Dogs 2 has severe stuttering issues on Nvidia too when driving fast. And of course CPU bound performance is not an issue anymore in Legion (or it's the game's developers responsibility). Nvidia's DX12 driver has overhead issues of its own, btw. Shadow of the Tomb Raider regressed on Turing vs. Pascal and is like ~15% slower than AMD (tests on the internet don't reflect this because they are GPU bound). Also RT shadows in WoW seem to cause a much worse CPU bottleneck on Nvidia (this is reflected by several tests though). If I pick a GPU nowadays, I don't do it because of the DX11 driver. Of course it would still be nicer if the AMD DX11 driver was better in some overhead sensitive games or if the Navi DX9 driver wasn't that bad, but well. Watch Dogs Legion allegedly doesn't crash anymore with RT and newest game update btw.
