    • Insanely fast
Style: Processor
upgraded from my Ryzen 7 to this Ryzen 9 3900X for gaming cache. First off its insanely snappy. Will run a bit hot even with liquid cooling. If you buy this get liquid cooling. So right out of the gate my RTX 2700 Super Founders Edition had insane eye candy and much better speed. Anything you through at it will open at break neck speeds. Your mouse will be your enemy. It will move entirely way too fast due to its processing power. This thing mops the floor with all the Intel Chips ive ever owned. Even my I9 chips dont game or compute as this chip does. Its a must have if you want to play video games and do insane amounts of processing. It operates on all buses on your system board quite efficiently. Ive been debating messing with my memory timing as I have AMD Ryzen Memory Ready RAM which automagically times with the system clock of the CPU and AMD Ready Ram will run at 3600 MHz. You must set your XMP/DOCP option in the BIOS. But Ryzen makes efficient use of PCIE 4.0 and its fast. You wont be disappointed other than it will push some heat but running any gaming on a 70 MEGS of video cache dedicated to video rendering makes this a seriously badd chip for anything you want to do. Its smoking intel and I have been an Intel Fan for so many years until this thing fell into my hands. All I do for a living is work on PCs Desktops Servers, and Land based internet I go home to this and appreciate all it does. It will not disappoint and will stay strong for years. This absolutely buries Intel. Worth every penny I put towards it. Now my Ryzen 7 2700 will sit in its plastic case. Trust me I had to do it. When I play Ghost Recon with my son it looks as though he is Sprinting it renders frames so fast. The game runs so quick with playing with other gamers your mouse will piss you off you will have to lock the frame rates on your mouse and they move so fast on your screen its simply amazing. Eye candy with games coupled with a NVIDIA RTX you will be amazed. Okay not a fanboy of Ryzen but I love this chip. See how it holds up and I am a verified user. ... show more

Motherboard: ASRock x370 Taichi Corsair Vengence 3200 RAM 32GB 500gb WD Black M.2 NVME boot drive 2 TB WD Black 7200 HHD storage drive 850w 80+Gold Cooler Master PS AMD r9 3900x Stock Speed (No OC) Cooler Master ML240L AIO Liquid Cooler Cooler Master H500P Mesh case Found that the 3900x was not in stock on launch date, 7/7/19. Set Amazon to notify me when available. Got the message hit the 1-click-puchase button faster than I ever have. The item was purchased 7/8/19 and shipped Tuesday 7/10. I received the CPU safe and well packaged on Friday 7/12, a day earlier than Amazon quoted at time of shipment. After updating the BIOS, and running a few final benchmarks on my Asrock x370 Taichi motherboard, I shut down the system and removed my 1800x (this CPU will go into my daily driver system and relieve my r5 1600 CPU slated to be installed in Mom's PC). Warning! Make sure to move the AIO fan wire out of the way of the CPU die and the cooler surface. I had a boot loop and overheating/shutdown session. Was able to get into the BIOS and see the CPU temp at 101c Wow! LOL no wonder it was shutting off. Anyway after seeing my stupid mistake, and re-seating the AIO cooler, the next boot-up took forever and 10 minutes to boot into Windows. Once Windows recognized the CPU and it was running, I started running some benchmarks. Now, I'm not a gamer, so again I am comparing my work load of video editing and production as well as rendering. With one commercial project alone, I my render time has dropped from around 20 minutes to 12 minutes... that's 40% improvement. I can render some commercial projects up to 4 times per work session. I've been very happy with the performance so far, but I'm absolutely blown away by this processor's ability. Rendering a 1 hour 1080p video usually takes an 1h 10m or so. I re-rendered last week's video and that time dropped down to around 42 minutes. My productivity is going to go through the roof. Spending $500 on one single item that is smaller than the palm of your hand can be mind-blowing for some people. It may also cause some heartache and possibly buyers remorse for others. Here's the deal, when you consider purchasing this CPU, you must do some research. Know exactly what you will be doing with your system to insure the performance gain is there. If you are a gamer, this CPU will play every game very very well. While it never claims to be the best in gaming, it is definitely meant for heavy work loads. What an outstanding and simple upgrade for a system that will provide another 4 years of great productivity. As a side note, I have been eyeing up an AMD Threadripper build for the past 9 months. My work requires high core and thread counts which enable the jobs to render much faster. I had already saved my money to invest into the 2950x and was still saving for the motherboard. Considering the fact that I earn a living with my PC, a professional workstation is in order. While it's exciting to order a new "toy", I hope you plan for something like this. It makes your purchase even sweeter when you "just know" you got a great product for a reasonable price, and it will do what you need it to do. Also, looks like I need to update the name of my system now LOL. It's not an 1800x any longer. Cheers! ... show more

    • Best value for money for especially content creators.
Style: Processor
In a word? IT'S A MAD BEAST. I have wanted something that could handle 4k and 8k video (codecs really play a part as all are not handled the same here). If you work with adobe products and you want a smoother performance then this CPU is for you and I never even see it go over 20% usage even when rendering. It's so good. As newer CPU's come out, this will be cheaper and will even be better value for money. Its mops the floor with its intel equivalent. Pros: * its fast, is beefy and its gonna chew through most of what you are struggling with now. A great balance for gaming and productivity. * Comes with a cooler (honestly it is the best looking stock cooler you will ever own) which manages to keep it tamed, just make sure to buy a case with high airflow. I dont recommend the NZXT cases because they dont have good front airflow. * Cooler comes with pre-installed thermal paste which is brilliant and it is very easy to install. (Look at the X570 motherboards for this CPU) Cons: * It gets hot. Oh it bakes very quickly so you will have to either buy an after market cooler or AIO to keep it cool over long periods of time if overclocking. Otherwise it's fine with the stock cooler Very impressed with the R9 3900x so far. I will be good for the next couple.of years for sure. ... show more
