The motherboard was received in brand new condition as stated in the listing. Solid Asus quality. The mb was in pristine condition. I had a few questions and the seller took the time to answer all my concerns. Good seller, good product, good transaction.

Amazing processor
I'm upgrading from a Q9550 and a AMD 965 BE and am continually impressed with the 9900K. Worth every penny as long as you aren't paying more than $510 for one. Definitely gonna need an AIO or beefy air cooler if you want to run over 4.3 Ghz's consistently. Pairs quite well with the Aorus Z390 Master motherboard. Two thumbs up. Don't let the jaded PC snoobs tell you otherwise, this processor is amazing. I'm using a Arctic Freezer II 280 AIO to cool at 5.0 solid clock. 32Gb 3600 CL 16 ram. No complaints.

9900k beats threadripper as workstation IMO
I was running a threadripper 2990wx in my workstation for after effects and c4d (and sometimes Houdini) thinking the 32-core beast would slay any tasks I threw at it. Not true! Viewport speeds in c4d were terribly slow... slower than my i5 from 2011... and ram previewing wasn’t much better. Apparently the lower (relatively) clock speed and less optimized architecture... possibly combined with issues in windows’ task scheduler... made threadripper a terrible workhorse for anything but rendering. Enter the 9900k. Less cores, but way faster clock and more streamlined architecture makes this thing way more responsive. I have never been able to interact with my computer faster. And the multitasking is insane. I was rendering with the cpu in c4d, while watching a YouTube video, while also ...

And the multitasking is insane. I was rendering with the cpu in c4d, while watching a YouTube video, while also working in after effects actively keyframing things and doing RAM previews all at the same time with no issues. Playback in AR was so smooth I actually forgot that I was still rendering. Maybe I got a lemon with my 2990wx, but the 9900k makes me very happy to be back on team blue. AMD is impressive on paper and in synthetic benchmarks but for me the proof was in the pudding.

Outstanding Processor for a Great Price
Fabulous processor. I came off of an 8700K which was fast but this is notably faster. Especially when loading up applications like Steam. Easy to overclock to 5.0GHz on all cores at 1.325v and easy to install as well. If you're planning to overclock I recommend a custom loop water cooling solution, or so what I do and use an All-In-One Cooler, where everything is assembled for you and just install it. eVGA's CLC 280 is the one I use and it keeps my OC'd 9900K down around 35C. Great for gaming as well. Fabulous processor. I came off of an 8700K which was fast but this is notably faster. Especially when loading up applications like Steam.

Honest, fast review of the i9 9900k Intel cpu
The i9 9900k imho is THE fastest processor money can buy. I have put this cpu through the wringer and it exceeded my expectations. Pros: Easy to install, fast, handles benchmarking with ease. Cons: The only con I could see is this cpu runs hot hot hot when pushed hard. However, a good cooling system (I use a Be-Quiet fan) or a water-cooling solution will take care of the con. Value: This cpu is not cheap. But, you get what you pay for. You want an over-sized calculator...get the cheap cpu. You want a monster cpu for that gaming rig of yours....pony up the extra cash and get the best.The i9 9900k imho is THE fastest processor money can buy.
