Which games will get great benefits from 8/16 over 6/12 this year, next year?
Both the 10600K as the 3600 will be fine for gaming only for the next 2-3 years, games won't magically utilize 8/16 over night.
You can of course go with 3700X instead of the 10600K to have 8/16, but for pure gaming the i5 does perform better, if we include streaming, sure, more cores do help.

2-3 years ago 7700k was the best cpu and look where are we now. By then we'll be long into next generation of cpus and gpus. There is already few games utilizing 8cores im sure there will many more.

Don’t like it don’t buy it simple really .

I did some testing tonight... my 3900x runs almost stable with 0,95V ... the difference:
Idle: 20W less, single thread 30-35W less with 18% performance loss, multithread up to 116W less with 14% less performance.
The difference to my previous postet results is, that they were aquired on a kind of 'naked' system and meanwhile there are tons of backgroundservices chewing off a bit...
oh yeah i forgot, that under Prime95 the max temp. dropped to 46°C xD - so, im eager to try 0.7V tonight.

Mind putting up the BIOS and AMD tool settings used for the different speeds/temps when you are done?

These XT models basically suck for value. I'm glad I didn't wait for their release date and I went ahead and built 3 weeks ago instead. $328 for a 3800x with a free Wraith prism cooler? Still feels like a good deal after this refresh release.

My stock 3800x settles in and runs all 8 cores @ 4.1Ghz under load, seemingly all day long. Which I suspect is the baseline average one could expect.

Here's a 12 minute stress test as I tried to nail down a silent fan curve. If I saw a graph like this running at 4.7ghz, that would be impressive.

Same as my 3700x with PBO and everything on auto, OCCT6.0.0 all core test pushes it up to max 62C
PBO disabled and setting TDP limit to max 1.28V it can easy do 4.3Ghz on all cores with lower temperatures, I prefer to have it clock down to 3.6Ghz when the cores aren't pushed to get close to water temps though.
