At first I hated it, was far too hot and it was scary seeing the temperatures rise to 90c instantly during a cine bench run. But after bios update, a reseat and switching to the Dark Rock Pro 4, everything is running smoothly.
At stock it hits 4.85, and I have it overclocked to 5.1, I have seen some users get as high as 5.2 and above. Overall, a fantastic CPU and I am happy to have switched this from a 3900x. All I do is play games, and a friend of mine who needed a CPU for work is benefiting much more from the extra cores of the 3900x.
