Blazing fast

Massively fast processor!
Had a few issues with the NZXT cam software not registering cpu temp, download of the beta bios sorted this, to be clear not a cpu issue.
The cpu has been very stable and extracts the most performance from games whilst streaming.
I am expecting video editing to be very fast and smooth.

Huge upgrade from i7-9700K for content creator.

This CPU is really phenomenon, playback 8K & 4K60P H.265 footage from R5 really smooth, unlike the i7-9700K I had before it just play slide show when I try to play the footage. No longer I need to proxy in Premiere to edit those footage too so a huge plus.

Excellent performance

I replaced my AMD 9 3900X with this. Considering core and thread count are identical the 9 5900X performance outstrips the previous generation.

At this price point it is the best performance for money CPU available.
