I swore off AMD for damn near two decades. Too slow, too hot, and it just couldn't match Intel at all.
A couple of weeks back, I took a new look at that with my new build. Ryzen 9, 3900x, 12 core, 24 thread. This thing not only outperforms my last build (duh, it was only an i7-7700), but stays much cooler (30-50c depending on the load).
I have to say, despite the cpu fan mounting difficulties (Intel still wins there with screw on design), AMD has won me back. Of course, my latest isn't your every day processor, but then again my (personal) needs aren't your every day needs
