All, Just finished reading an article that is concerning. Over the last couple of days, the decision was made to choose the above CPU for a friend's PC. Use will be Premiere Pro (primary upgrade is live edit, not rendering), some gaming and general use. See BOM below:

After reading this article, I don't know if we made the right decision. We based the decision of a variety of resources including testing videos and reports from Puget Systems. I would appreciate any comments and guidance.....thanks.

btw, what huntlong said about AMD seems to be the case, but everytime i explore AMD CPUs i find a whole different set of issues facing AMD users (mainly seem to be picky about the RAM) and i'm too old to climb any more learning curves

fwiw, i found my 9900k over in UK, price delivered was $648 and was here, ordered 5:00PM their time on Tuesday, and arrived yestered just after lunch http://www.tomshardware.com/answers/id-3819336/9900k-intel-produce-day-week-month.html#21474559

with their scarcity here in the US, that $530 price was amazon's pre-order price, but after Newegg emailed me they had a shipment in, i called in less than 60 minutes after their email was sent and they were sold out. I asked the CSR when the next shipment was...

Only my personal opinion but Ryzen seems to be the way forward for now. I’ve always been on team Intel but they are really struggling right now. Ryzen 3 is set to release the first half of next year and is rumored to increase the IPC up to 15% and early engineering samples are at 4.5ghz. This would put the next gen Ryzen ahead of the 9900k and it will still work with current AM4 motherboards. You can also buy almost two Ryzen 7’s for the 9900k. So if he went with the Ryzen 7 now he could upgrade to the next gen in a few months and still not be out as much as he would be for the 9900k.

FWIW - i just rcvd my 9900k and that very same motherboard, asrock taichi but looking past what that article sez, i am looking forward to the 5.0 GHz clock speed

i do a lot of rendering using the rig in my signature below (5960x is 8 core / 16 thread cpu) - i don't use Premiere Pro so i can't give you a reference specific to it.

I'm not much of a OC tweaker, but got my 5960X to 4.0 GHz from it's native turbo boost of 3.5 GHz, and wasn't very happy with the reduction in render time for any given video file compared to my i7-4790(non-k) with 4 cores/8 threads - on a 40-45 GB file, maybe a 17 - 20%. I got around to tweaking and got the 5960x to 4.3 GHz and the improvement in rendering speed was noticeable, to the order of 25-28% shorter render times than the 4790 CPU - nothing to write headlines over, but decent enough that i started to feel maybe the $980 i'd spent on that CPU wasn't that bad an investment. If i can hit 5.0 GHz i'll be a happy camper, and yeah

keep in mind, i suspect the writer in that review may have an agenda - the comparison to a 2950X i wonder about, it's $300 higher in price, and twice the cores & threads than the 9900k (2950x is16 cores/32 threads) and i've already seen first hand that just having twice the core count didn't have as much of an effect on productivity as i expected.

So now i'm banking on OC frequency. Yeah it's a hot beast, but i think it'll be manageable

Thanks for the reply @Ralph,

Actually since I read that article and posted it, I found out that the writer does have an agenda of sorts.
The results in some cases don't equate with other data......

I do appreciate your perspective; hoping that once Intel supply increases, prices stabilize.

I asked the CSR when the next shipment was due in, and he was kind enough to check - came back next shipment is due Nov 30th and they expected 100 units on that shipments. Think about that - 100 units for newegg USA. If you're waiting for an amazon pre-ordered unit to be delivered, it may be awhile
btw, the one i found is an "OEM" unit, ie no retail packaging and 1 yr warranty vs the 3 year warranty on the retail unit

Wow, they really are hard to get. Well, my friend can wait a bit; hopefully Intel diverts more manufacturing capacity to make more...which theoretically should stabilize the price. We'll see.

Good to hear that it is working well for you. What are you using for a cooler?

haven't assembled the system yet - the 9900k just arrived yesterday and i've got two decent size jobs to run - i'm hoping to assemble it Sunday - go to that website though and check their review postings -

i'll be using the same cooler i am now, a noctua D-15S - the ram i ordered is definitely on the tall side (G.Skill TridentZ )

no, and before i go liquid i'll do what this guy did near the end of his video (that's berbauer) - the 9900k for whatever reason, people have discovered has a thicker IHS than earlier CPUs - stainless steel is not a good conductor of heat, and making it thicker doesn't help, actually makes it worse

after delidding his 9900k and not getting very good results, he sanded about .008" (8 thousandths) off the IHS and damn if his temps didn't go from, iirc 96C down to 83 - 84C

here's the video link - be sure to drink a couple cups of double expresso as he definitely did before making it - i couldn't hear as fast as he talks - but the good stuff is at the end https://youtu.be/r5Doo-zgyQs

I'm an old fart, and it's never been an inclinatio of mine to put water near electrical equip - if it leaks, you're talking a lot of expensive components going out.

I suspect someone with A/C background, will come out with a mini-A/C system and might even be able to get away without needing a pump - Freon (and whatever they're using these days) self compresses to a liquid form when it goes thru the outdoor unit, and then is pumped to the evaporative unit inside the house, where it turns back into a gas when it is heated by the air passing thru - that should work on a CPU, the issue may be it wouldn't work well enough

as a last resort, i have a grandson i'll pay to stand next to the computer and shoot the noctua cooler with CO2 from a fire bottle - CO2 will freeze when released as a gas.

Well, let me offer this from one old fart to another, they make AIO (all in one) liquid coolers, and from what I have read some are quite efficient and safe (no leaks).

There is a forum section here "components" that is where coolers are discussed....check it out.

jay on youtube had the same issue with his intel cpu. they found out the intel cpu cover was not flat. they spun it like a top and before the sanding it would not spin as it was not flat. after the slight sanding it spun and ran cooler as there was more area hitting the heat sink. one thing to be care full of is if and when intel gets to 10nm. will they force people like they did with coffee lake to get new mb just after there newer 200 chips dropped. the 390 mb had to come out to power the 9000 chipset. the vrm on these mb are not the same that are on the x370 mb.

i was asking smorizio for the youtube link

as far as the AIO, sorry, water looks for a way to leak, at least that's my experience with it - that's why it's called water

my noctua D15S, when my current cpu has a TDP of 140W and generally runs higher because of the OCing, when it's at 100% load i see temps in the mid to low 70s, so i'm comfortable i'll be okay with the 9900k. Voltage management does a lot in keeping temps down

A warning - DO NOT FLASH THE LATEST BIOS (P1.51) RELEASE FROM ASROCK FOR THAT MOTHERBOARD

I flashed mine this morning and i'm thinking it's bricked, unless Asrock has some magic way of getting me into my BIOS

mine still had the initial P1.20 BIOS, and i didn't touch P1.30 or P1.36 (which has now been removed from their support page, but P1.51 indicates improved OC performance and removes the power limit

I posted about it in the motherboard forum http://www.tomshardware.com/answers/id-3824436/updated-bios-asrock-z390-mobo-post.html

The frustrating part is, while Asrock has a backup BIOS chip on this board, there's no mechanical switch to change over to it - you have to in BIOS, which i can't get into. My earlier Asrock X99 board, you simply turned the computer off, turned off PSU, moved switch from BIOS 1 to BIOS 2 and turned computer back on. They probably saved 3 cents doing away with that switch
