    from completed build Black X Blue 3950x Build

    The best all-around CPU you can buy without entering into the HEDT space. However if you only care about FPS at 1080p/1440p, you will be better off with the new i9-10900K. For gaming, absolute frequency still wins.

    from completed build Black & Green

    16 cores and 32 threads of blistering performance. It made its competitor slice the prices in half.

    Running at stock speed. PBO adds just a few percent of performance, with a large increase of power consumption and heat. And manual overclock means no core boosts to 4.7GHz.

    Cinebench20 performance numbers: Stock: ~9260 (~3975MHz, 1,1V, 57°C). PBO: ~9660 (~4125MHz, 1.3V, 75°C). Manual OC: 10100 (average 4300MHz, 1,28V 75°C).

    from completed build Dream Build

    Loved the 3900x, minus the first few BIOS issues, the kinks worked out for me and it was solid right up until I switched over to the 3950x, which has been golden. Great chip. A little warm, but for 16 cores its kind of expected. Jumped ship on Intel (Nothing to do with fanboy ********) after I purchased a 9940x last year for almost $1500, for them to release the 10xxx sku for half the price. Granted no one was there to challenge them, blah blah blah, they're still scumbags and I will stick with AMD unless for some ungodly known reason I have to pick up an Intel rig.

    16 cores, 32 threads, what more needs said! Perfect for productivity, runs a lot of heavyweight code editors, Virtual Machines, Docker containers and emulators simultaneously with ease.

    from completed build UPGRADED. There, I did it!

    What can I say...its the fastest processor I have ever had. Doesnt' overheat, set it to 4.35GHz at 1.4volts runs like a champ. Highest temps for me is 67-77 according to Ryzen master during Cinebench and Afterburner benchmarks.

    from completed build 3950x / 2080 Ti hybrid

    Runs a little hot from what I'm use to while idle (29-32 C). Under load it hits temps of 71-75 (71 C being the reported average). Use Ryzen Master to check temps, as other programs do not give accurate numbers.

    Very fast- factory boost is pretty awesome so far.

    from completed build Learning as I went build

    This is ridiculously fast. I don't have a ton of experience to compare it to, so for a real review you can turn to all of the existing content that is already out there. What I can say is that it was a snap to install. No worries at all and it works exactly as advertised.

    Wow. Blazing fast. Blows my old 6700k out of the water; it's over 4x faster in cinebench.

    from completed build Slight Overkill - New Gaming PC

    Very expensive CPU, and complete overkill for my needs, but its fast and apparently runs cooler than the 3900x. If you actually have a need for this many cores and can afford it and the supporting hardware, it will not disappoint.
