First time, I had same drive. Then I read that it is better to have different drives, so second time I installed Windows on a different drive. It still managed to mess up Linux.
It is highly hardware and game dependent. I can run any game that came before 2019 on my 1060 on both with similar performance. Anything that came after that is hit or miss. For example, Until Dawn remake does not launch on linux but runs smooth (barring some menu hangs) on Windows 10.
Some people have estimated 8x energy use for 5 as compared to 4 but the model is not 8x better, this has to be a clue to them that increasing power is not the way. But nope, trillions of dollars more will fix it.
I am going to enjoy the fun when code starts bugging out.
