so will the Core i7-9700K come with a stock coooler?

Solution
Of course not. Intel expects people buying their high end CPUs to supply their own cooling solutions which, in all honesty, is better off anyway seeing that their included solutions have been woefully inadequate for quite some time.


"Worth it" is subjective.

Ryzen processors, especially the 2700X, have shown that they are great CPUs and far better than Intel's offerings when doing multi-threaded workloads. Intel reigns supreme for gaming... but AMD isn't that far off. Plus, AMD's offerings come at a cost benefit and include some of the best cooling solutions around.

It's really a matter of what you're doing and how much you have to spend which determines the direction of a build. AMD isn't a "poor man" CPU and really never has been though Intel fans sure enjoy tossing that slight around. Do your own research, draw your own conclusions, and be happy with your choice no matter which vendor ends up being the selection. That's all that matters. The rest of it is strictly noise.
 


Except for BF5, where the differences for min FPS /average FPS have the 8700K faster than the 2700X by 35% and 29%, respectively...

And as the 9700K will be slightly faster yet..doubt that will change.
 


It's still in beta. Based on that, it doesn't mean the game will remain in the currently set stage. Things can and very likely will change prior to full release because the current optimization is terrible. As there are no tests yet available for the 9xxx series, anything out there is speculation or untrustworthy.
