    I'm about to upgrade to a new machine after console gaming for the last 2 years and I have 2 options but I can't decide.

    First is a 9900k, Asus Tuf Z390, 32gig 3200mhz ram, MSI 2080super, case, PSU and 240gig SSD for $2750aud

    The other is a 3900x, Asus Tuf X570, 32gig 3200mhz ram, MSI 2080 super, case, PSU and 240gig SSD for $2650aud

    The intel build comes with a 240mm AIO rad and the AMD just has the stock wraith... Either comes with a 750watt PSU but I have a 1200 watt Corsair ill put in from this pc instead. I can upgrade to a 2080ti for ~$470 more but it doesn't seem worth it at all

    I'm primarily gaming so that's my main focus but I can't help thinking the AMD would probably be better in the long run. I have spent hours reading up on the pro's and cons of both in reviews but I can't make my freaking mind up. My current monitor is a 55" 4K OLED with dual 27" dells on the side in portrait so probably mainly aiming at 4k play potentially ruling out any low res advantage Intel has... Anyone running either CPU care to help me try and decide?

    Work-wise AMD is better....CPU´s have more IPC and if you take into account the 3900x you have more cores, so better render speed....

    Gaming-wise Intel beats AMD in its raw state....but when you put everything into account....intel only has more FPS when core speed is a factor........with this said you can only talk Intel until you reach FHD resolutions.....passing that resolution....CPU speed is no longer a factor because games start to get GPU intensive instead of CPU intensive like in low resolutions..

    .....and since you pack a 2080 Super, I bet you will not be playing at 1080p or less....and also assuming that you are not a "single threaded brain person" ;)...

    If 1440p Gaming, then Ryzen is notch better.
    Game cache + good RAM and we have a winner.

    I would give a try AMD.
    Dunno what u need 32gb for, imho 3800mhz 16gb with cl15 or16 is better option, especially for min lows. Or bigger faster ssd, like m510 corsair m2 drive.

    And if u do not play 1080p esport games, 9900k is just waste of money.

    I went through this same decision about a month ago.

    My last PC build was a i7 920. It lasted a long time for primarily gaming. I wanted to have the same longevity out of the next build.

    If it wasn’t for the x570 chipset I would have gone Intel for the slight edge during gaming FPS.

    Owning the Asus TUF Wi-Fi, I highly recommend it. I have Windows on the M2 and the games on an Evo 860 SSD with a stock clock 3800x 16GB 3200. Very fast PC and game load times are really quick now, can’t wait to put them on the other M2.

    AMD has stated they plan to release at least one more CPU for the AM4 socket.

    I have an Asus Strix ROG 2070 Super at 1080p 144Hz.

    I love this PC!

    BFV, Control, Outer Worlds, Borderlands 3 and Red Redemption 2 all run smoothly. I’m one of the lucky ones I guess for RD2.


    Good luck with the decision.

    I was asking myself the same question and just bought the 9900k. This decision was not an easy one but it's nearly impossible to find a 3900x right now (and the prices are just too expensive) . I made bad experiences with new products in the past too and became cautious about this.
    But i wouldn't say i did the right choice for the future.

    Get the 2080ti if you want the fastest gaming rig mate it blows the 2080 super out of the water, seems a waste buying all the other top range equipment and then dumping the best gpu?

    All around performance 3900 hard to beat. Gaming those 9900’s and 8700k get the job done better if you’re just looking at very high frame rates.

    3900, Intel got too many security issues.

    I went the AMD (3800x and x570) route to replace my 5ghx Intel 2700k and the PCIe Gen 4 P600 drive on the x570 mobo is outstandingly fast, and on some games, certainly DCS flight sim im pushing well over 16gb of the 32gb i have.

    I am very happy with my Ryzen 9 3900X, it's fast and at stock it can outpace my Core i7 6950X@4.2GHz (10core/20threads).

    I was hanging on for a 3900x but couldn't wait any longer. I might swap out my 3800x for a 3950x though.

    If you are not going to be using the rig for anything more taxing than gaming, do not waste money on an X570 board. Better off purchasing a good X470 board and putting the money saved on the board towards something else. As for gaming, best cpu is still Intel. Keep in mind that the current socket was officially supported through next year and that has been the last bit of info anyone has at the moment. Along with what has been stated in previous posts, AMD for jack of all trades, master of none and Intel for gaming. Enjoy the new rig.

    As a current user of an AMD 3800x, I would not say it is a master of none. Plenty of comparisons provide the proof.

    Ditched my 4790k 4.4ghz / 2400mhz 32gb DDR3 CL-11 system for an AMD Ryzen 3700x / 3000mhz 32GB DDR4 CL-15 system and very very pleased (the RAM was on sale for dirt cheap when I got it, which is why 3000mhz vs 3200 or 3600mhz). Bought a dirt cheap x570 motherboard - cheapest one I could find - the AsRock Phantom Gaming 4 x570. Got 50$ off the board with the combo price at Micro Center. Paired with a 1TB house-brand pci-e 3.0 NVME drive, it's a great running. It does all my 4790k did and more, with plenty of performance extra. It whoops through content creation, and in gaming it's no slouch either (it's actually a notch faster than the old PC in single-threaded tasks and anything that uses the newer instructions the old machine didn't, it's much faster). No more hitching up and lagging, and the extra cache memory on the CPU is also very very helpful to keep things smooth.

    Any x570 motherboard will do, currently Micro Center has it pretty cheap if you have one nearby, with a combo discount with a chip.
    3900x is about 500, but the 2700x is currently on sale for 130$, with 3 months game pass, with a free game, plus a 30$ discount off any motherboard. The 2700x is a pretty great chip if you want to get going with PC's, but it certainly won't keep up with the 3900x if it must be told. The newer faster chips are generally always a bit faster but this generation (from 2000 to 3000 series on AMD) got about 8~15% per-clock increase.

    Down the road the AMD board will be able to upgrade to at-least an 16 core processor, with up to 128gb of RAM on the 570 boards or 64gb on the 470/450 chipset line. You also get pci-e 4.0 on x570 boards, something the intel can't currently match HOWEVER not a whole lot outside of NVME drives (or AMD 5700 series video boards) use it quite yet. That being said, it's always smartest to buy into the newest platform, and if you're spending 500$ on a 3900x CPU, it's best to put it on the x570 board - even a cheap one (anyone but the MSI MPG, that's the worst one of the lot) VS the only-30~60$ less on average B450/x570 boards - the 400 series chipset will need a bios update (and an older CPU to do it unless it has 'BIOS flashback feature!) to run any 3000 series CPU if it does not have the 'Ryzen 3xxx Ready' logo on the board in Orange.
    So TL-DR get an x570 board and the 3900x, and don't let anyone tell you 'you don't need 32gb of RAM', just buy 2x 16gb sticks in a kit 3200mhz~3600mhz speed with as low latency as you can afford, and it's off to the races. If you do anything OTHER than game, the extra memory will come in quite handy.

    You can use the stock cooler that comes with the 3900x, or you can upgrade to a 40~50$ air cooler to keep it running fast longer, but the intel 9900k will definitely NEED a water cooler, save for maybe a Noctua D15 etc. Conductonaut / Thermal Grizzly is also good names for thermal paste, if buying a cooler get good paste too. Just make sure not to mess with 'Liquid Metal' unless you wish to take the risks of possibly shorting something out if it squeezes out and drips down (usually onto the video card!), liquid metal paste IS conductive, Thermal Grizzly is not.

    Would recommend a nice Fractal tower, they're like LIAN-LI in quality, or a Corsair unit. I use Fractal Design's full tower model (hard to find anymore!), as they offer LOADS of room for my 40-year-old hands, and lots of breathing room for the parts. I care not about LED's or RGB's, so I can't help you there. I just like quiet and dark.

    Why do they not make computer cases where a light comes on ONLY when you open it up to work inside?
