If you're primarily going to be playing games I would recommend a 5800X3D over the 5900X. Maybe also look for a used 6700XT/6750XT/6800XT instead of the 7600. Everything you have will work just fine with Linux. You don't need more fans.

Are you using pcpartpicker? That site is pretty good about flagging potential issues in a build. They have measurements and power ratings and slot configurations for basically everything so they'll flat a build that has incompatibilities

Noooooo!!!!! Your motherboard is not compatible with CPU and RAM. I will edit this post once I have formulate my reasoning, I want you to hold off buying this system based on ptevious comments

https://pcpartpicker.com/

Right up until the day they're bought out by shitheads, that's the place to go for setting up a home build.

It verifies compatibility to a level you'd never even think of, including heatsink and graphics card dimensions.

Why are you getting a 5900x CPU? Are you going to be doing a lot of CPU heavy work? The 5900x isn’t really a gaming CPU it’s more of a productivity CPU. Because of some quirks about how it’s made the 5800x (8 core) can typically perform better on games and be cheaper.

Also the 5800x3D is a beast. I’d highly suggest going for that if it’s close enough in price.

Another anecdotal comment. I got a curved monitor and IMO it was not worth the extra cost vs. a flat one. I think these things are kind of gimmicky unless you are buying several of them and building a simulator (I do flight sim and I don't see any benefit with just one, even).

So far I would say everything should be good. Your pictures are just missing one really important component, which is the PSU.

Edit: As others have pointed out the CPU is actually an AM4 socket so it wouldn't fit or work with the mobo you have there. Kinda missed that, sorry.

Damn RAM has gotten cheap, I really should get a motherboard that accepts DDR4

• Only one big problem here: the Ryzen 9 5900X is an AM4 Socket CPU but the motherboard you have selected has an AM5 socket. This board will not work with the AM4 CPU or the DDR4 RAM. The DDR4 RAM is correct for the CPU though.

• The CPU requires a dedicated cooler, typically an all-in-one liquid cooling kit (though fan kits exist as well). If you do not already have one, you will need to obtain one. Intel CPUs typically include a basic fan and heatsink, but recent AMD CPUs have more intense cooling requirements and these are left to the aftermarket. AIO kits usually come with a handful of adapters for both Intel and AMD, but you want to make sure a bracket for the AM4 socket is among them. I had an old AIO system when I built my new AM5 machine, but AM5 didn't even exist when this AIO kit was manufactured.

• Not a major problem, but worth consideration depending on your intended workloads: With 16GB DIMMs you will max out at 64GB of ram, which is A LOT, but with 24 threads, that's a bit over 2.5GB per thread. With two DIMMs (as shown), that's a bit over 1GB per thread. You will struggle to use that CPU to its full potential when it comes to doing things like compiling somewhat complex software. In practice, I have found 4GB/thread to be required when compiling things like Chromium (QtWebEngine), and about 2GB/thread for things like Firefox. If you are not compiling (major) software from source code or running Gentoo this likely isn't a problem, and you can always limit the number of jobs to work with the amount of memory you have available in the odd case where you end up doing things like this.
  That said, I can't seem to figure out definitively what the maximum RAM limit is for this CPU or chipset. If it is not greater than 64GB, there is no point of getting DIMMs any larger than 16 GB. The X570 chipset (fanciest, among several in the AM4 family) apparently supports at least 128GB, but this will also depend on hardware support in the motherboard. Just because a motherboard has this chipset doesn't mean it supports all of its maximum capabilities (i.e. PCIe lanes, memory, overclocking, etc)

I never used DDR4 personally, but from what I hear, the difference between DDR4 and DDR5 is marginal, but DDR5 comes with the added headaches of "training." It can take upwards of 15 minutes for a DDR5 machine with a lot of memory to boot for the first time. I was nearly ready to RMA my memory before I figured out this was happening, and I had to flash a UEFI firmware update to ultimately get 128GB working.

I'd bump up the PSU from 650 to 750. Everything else looks good

One thing you need to keep in mind in case you didn't already know is that this is an older AM4 system, and if you want to upgrade in the future, you'll have to get a whole new motherboard, CPU and memory (AM5 doesn't support DDR4 RAM).

If you want to save some money, you could go with a weaker CPU, that one is overkill for gaming which is more GPU dependent anyway.

The infinity fabric speed, the stuff between chiplets wants to run in a 1:1 ratio with ram, so you can squeeze a little more out of that cpu if you get 3600 ram.

Ddr4 runs at half the rate is says (double data rate) so 3600 runs at 1800mhz which will match 1800mhz of the infinity fabric. Some chips can go higher but it's not guaranteed

You don't seem to have a CPU cooler (the CPU in your screenshot says cooler not included) which is mandatory. A Thermalright Phantom Spirit 120 EVO will almost assuredly be the move, thermalright is KILLING it right now in the air cooler scene. I'd question going for the 5900x when something like the 5800x3d exists and can be had for fairly cheap if you live near a microcenter, but it seems like you're dead set?

On NVIDIA vs AMD, I don't begrudge you for avoiding NVIDIA due to controversial decisions, but on the other two points:

• the price difference isn't that crazy in my experience, and in exchange for the NVIDIA premium you get killer apps like DLSS, frame gen, Reflex, superior raytracing, while the AMD counterparts lag noticeably behind. the slight edge in raster performance from AMD doesn't seem super worth it currently IMO, but that could always change!

• PopOS specifically actually has great compatibility with NVIDIA from what I've read, although I believe it depends on the proprietary drivers which may not be your cup of tea

Are you in the USA? You should be able to get something much better balanced for $1.6k, let me cook.

drivers' poor performance on Linux

Not necessarily true. If you have an older card (older than the 1650/older than 2020) you're fucked but newer cards should actually be supported. By the end of the year Nvidia should not be an automatic downgrade of an experience compared to AMD. But yeah they're expensive, ruled by the richest capitalists in the world, and their power efficiency is hot garbage.

Pop OS on it as my primary operating system.

If you're getting primarily a gaming PC then I would recommend checking out Bazzite because it's all batteries included with support for Steam's gaming mode (basically getting the Steam deck functionality onto your PC) with minimal setup required. POP!_OS is still going through a heavy transition right now into COSMIC so I wouldn't recommend it right now until POP!_OS 24.04 drops. I've used it on my own gaming pc with an nvidia card and it worked flawlessly (minus the green company problems).

You probably need to buy front intake fans for the chassi as those aren't included. In that price class there's phanteks p400a, lian li lancool 214 or 216, fractal meshify c, that have all done well in tests and have some included fans.

I went AMD first a while ago, be prepared for some games not to work (R6 SIEGE... years ago though, not sure how it is now) without some workarounds and stuff.

Also, I don't know, but you could consider Bluetooth in the MOBO as well. My PC is just general use and gaming (built for like £800 5 years ago) and I regret not having Bluetooth without using an extra chip and all that.

Also I'm not seeing a case on there. When I was new to this stuff I bought the wrong sized case initially and had to send it back. Make sure it fits before you buy.

I have a 5800x3D and it's a beast. I'm very happy with it. 5700X3D is about 10% less beefy on the compare charts.

5600x3D vs 5700x3D vs 5800x3D

I HIGHLY recommend a good AIO. 2x 280 or better setup. The 3D Vcache generates extra heat. (Heat that goes in your case. An AIO pumps that heat out via a radiator keeping your board and your CPU cooler)

Along with that don't cheap out on your thermal paste! I got the Corsair XTM70 it's like $20.

comparison test

It is a very THICC paste that comes with it's own # type stencil (put stencil on CPU. spread paste over stencil . Remove stencil. Perfect application.) Used Arctic Silver in my previous build it was fine...for an Athalon II.

Gaming Jesus took some issue with the H5 case

Ugh I need to stop drinking so i can afford a new cpu so i can keep up with how much they keep slowing down Victoria 3 in every update
