Already bought the 5900X right when the price drop came, and couldn't be happier :D. Initially, I wanted to buy the 5800X3D but considering the slight perf improvement on games, and not having cores as many as the 5900X, also a little bit more expensive than 5900X in my country, I decided to pick the 5900X instead.
