Good, but not great

Pros: Good performance out of the box
Good memory performance

Cons: too hot when overclocking, fine on stock speeds with a good AIO
RyZen 2700X is a better CPU overall for the money, save money and put it towards the graphics cad.

Other Thoughts: save $200 and buy the ryzen 2700x, and put the money towards a better graphics card.

Wicked fast!

Pros: Upgraded from a i7-2600, to compile my project in Visual Studio took 2 hours, now takes 40min.

Cons: A bit pricey

5/ 5

Pros: Straight hauls, and then some! Runs fairly cool on a Corsair H 100i AIO. Fairly energy efficient at 95 watts. Makes my almost 3 year old GTX 1070's shine bright! After doing my homework, I decided on this CPU. If you have to have the fastest, (currently) look no further. There's a lot of haters out there posting negative reviews on You Tube. If all you do is game, and don't care about 4k gaming, you may want to consider AMD's offerings. This is not a bang for the buck CPU!

Cons: Price, to a point, but speed and stability right out of the box has a price! Doesn't overclock very far past it's stock turbo speeds, but what do you expect? 6GHz?!?!?!? Not yet!

Other Thoughts: Coming from a 10 year old X-58 platform with an Intel i7 980X 6-core that was only OC'd to 3.6 for daily use and had it up to 4.4 for smashing benchmarks, this i9 is a noticeable improvement. I ran all my benchmarks with "MULTI-CORE ENHANCEMENT" enabled in BIOS, and I obliterated ALL of my 3DMark scores! Games load noticeably faster than before and I am able to finally play the first Crysis game at High settings at 4K resolution! ( LoL ) Comparably, my super pi at 1M went from 10 seconds, to about 7.75 seconds!
When I upgrade to a new platform, I want to see a DIFFERENCE. That's why I go so long with my builds before switching platforms. I want it to be a significant upgrade. I already had some good parts to migrate- 850 watt PSU, 4 TB WD Black Edition for storage, Cooler Master HAF 932 case, LG BluRay burner, and a Corsair H100i AIO water cooler for the CPU. It kept my costs lower than actually building a so-so modern mainstream gaming PC. I guess if I am ever able to upgrade this CPU and stay with the same chipset/platform, maybe intel will have a 10nm CPU with more cores or the same number of cores, but faster clock speeds. Only time will tell!

Great CPU.

Pros: Love it, got it for a retrofit of my old AMD 8 core. Much better, definitely needs some liquid cooling for those higher CPU temps but it is so nice to be getting over 100 frames in games like EFT and ARMA. I say bring it on now this thing is a beast.

My PC start time is less than 5 seconds, it s amazing, boots quick everything CPU heavy loads extremely fast. I think Intel finally converted me.

Cons: the only real Con I have so far is the awesome packaging did not want to open... it took me a good five minutes to get the thing out of the Cube it was sealed in.

Other Thoughts: So far I definitely say you need liquid cooling for this beast, definitely need to be able to utilize this thing, Its amazing at what it does.

Happy with purchase - 9900K

Pros: It's an Intel
Running at 5200MHz
Solid specimen

Cons: Temps! I would rather see cooler temps on this CPU. My GPU loop runs idle at 23 on a 360x38mm custom loop while the 9900K runs idle at 35 and pushes over 70 quite easily and over 90 during synthetic stress loads on a 360x38mm custom loop. In it's defense it does push some serious wattage during stress tests.

Other Thoughts: I came from 5930K to this and the 9900K is way faster in synthetic benchmarks. It works great with a Passmark CPU score of 21524. This is in the 99th Percentile. I have it installed on an EVGA Z390 FTW board with G.Skill 3200 CL14 memory. It's running at 5200MHz with voltage around 1.26 and bumping to 1.34 occasionally.

The system is a custom dual loop with the CPU and GPU on seperate 360x38mm radiators. The CPU runs very warm under stress tests and benchmarks pushing beyond 90C on all cores. I have a couple of threads that will crash in Prime95 at 92C. The rest will touch 100C during these tests without issue.

Lockheed Martins Prepar3d v4.4 with lots of add-on scenery runs the temps up to 70C. I just don't see a whole lot of improvement in P3D over my 5930K. I expected much more from it.

No EVGA Z370 C

Pros: Can't tell

Cons: Not sure I would notice

Other Thoughts: EVGA bios won't support i9 without and upgrade to bios, which means pay for an RMA even if it the board is functional and not broken, bought 2 to try keep a real time point of sale up and running for a business. Tech support gave proven incorrect advise, and I can't tell you, I have spent enough to buy a new car with them, and loved the company at first, but this tech support has me all but gone as a customer. Will update and the much anticipated CPU later. Thank you for reading.

Great cpu so far

Pros: fast
great for studio daw and games

Cons: none so far

Other Thoughts: I had a i7 6700k build with thunderbolt 3 and liked it, I paired it to a 1080ti. Everyone said I didn't need to upgrade but I felt that 8 faster cores are better than 4 haha. I was right though, second I popped in in, didn't even need to re install windows 10 either, and everything is quicker overall, between loading( not that the i7 was a slouch or anything) , running programs studio daw bouncing and gaming, the extra cores helped out in destiny and BF 5 I noticed big time, mainly because of the extra physics needed for big action sequences this new cpu doesn't slow down my framerates, it can hold really really well. A worthy upgrade for sure, everyone said wait for the ryzen 3 this year, but the biggest drawback is the lack of dedicated thunderbolt support, plus I feel that their cpu's are slated to be equivelent to this with a slightly lower power draw, but at 95w I'm not worried about it
