Why would you want one though? For marketing reasons they can't really do a 6 core 5700X after the 3700X was an 8 core, not like they could do a significantly higher clocked 6 core anyway, so it would have to be a lower clocked 8 core.
If you want an 8 core that is slower per core than a 5800X (or 5600X for that matter) you can just buy a 3800X(T).

Ok, makes sense then.

Multitasking is sort of independent of multi-monitor though. You can only click/type in one window at a time, no matter how many you can see, so it's just a matter of how many programs are running and the number of monitors doesn't restrict that. Still, 16GB is the right choice.

Well the B550M PRO-VDH is much better in that regard than others or even previous generations of the same. It does have 4 RAM slots, 3/4 fan connectors, good enough VRMs and CPU-less BIOS update (those are usually the things missing on the cheapest mobo of a lineup) but the less than ideal onboard sound, no USB 3.x (only 3.0) and no external USB-C, only 2 PCIe x1 slots and no second x16 slot do remain, so be aware of that. It's not a problem if you don't need any of that but those are things you notice years down the line when you can't do anything about it.
Also never trust 4chan.

So you're getting 145-150 fps at 1440p windowed. And you want 144fps (I assume you mean fps not Hz, if your monitor's refresh rate is unstable I'd be very worried) at 1440p, maybe windowed, maybe fullscreen?
What exactly is the point of this upgrade then?

Why would more monitors need more RAM? Do you think higher resolutions need more RAM too? That's all VRAM, the GPU, not RAM. Not that is a noticeable amount for desktop usage or in TF2 anyway.
No reason not to get 16GB anyway though. Could also go faster, 3600 MHz or something like that.

Don't cheap out on the mobo, you'll regret it.

244 seems oddly specific.
I don't think you can get "stable" fps in TF2.
Also I've got no idea which CPU would be good enough for 244 fps with those settings (6s? HL? pub?) and which would be overkill and I don't care enough to benchmark and extrapolate.

X570 for a 3000 would be a waste and generally buying a 3000 now doesn't make much sense.
Wait.

Not sure how you'd know your pc is "close to dying". Usually that's just windows. Or maybe one part is dying. E.g. nice graphics artifacts mean the GPU is dying.

To be honest you shouldn't even have bought a mainboard before buying a CPU. Not like any of this will get more expensive so why buy it earlier than you need to?

5600X or keep the 7700.
If the goal is better source engine performance why bother upgrading anythng but the CPU (and mobo obviously)?
A new GPU isn't going to magically make TF2 not CPU bound.

Get a good CPU, mobo, maybe RAM if you can afford it (makes selling or reusing the old parts easier as well), reinstall windows, maybe overclock and see how that goes. I guarantee you that reinstalling windows and better RAM (TF2 is weird) will have a larger impact than even an RTX 3090 would have.

PCMark is not that great, especially not when judging source engine performance. The benchmark thread is much more accurate in that regard.
The PSU is fine, it got two 8 pins. It's an ok design, not some ancient garbage with half the wattage on the +5V rail.

6800XT actually seems fairly reasonable if you're going for 4K.
Obviously wait for benchmarks and see if it gets you the performance you want in the games you play before buying anything.
Also check your PSU, it'll draw more power than an RX 580. 550W should be on the safe side.

The 6800XT got better encoding (how much better we'll have to wait for reviews), if that doesn't fix it there's probably something wrong with your settings or connection.

#3751
It's TF2 so it's the CPU.

#3752
Get new GPU and use GPU encoding (though you can even try that now).
Then maybe get a 5600X if for some reason you still think you need it.

I don't think there's a rule "you have to spend at least X Dollars before you're allowed to buy a CPU with more than 6 cores".
Also if he were to keep the 580 it'd be virtually impossible to even reach 1500$ without doing something utterly retarded like buying a 500$ mobo and 500$ RAM.

Anyway, this is not a question of "only buy X if you spend Y dollars", it's a question of usefulness.
Even if he had a budget of 3000$ I still wouldn't recommend 12 cores if nothing he does uses more than 4.

#3747
Why are you upgrading?
If it's for games you probably want a new GPU. If you're getting a new GPU you'd better have a very good reason for using CPU encoding instead of GPU encoding for streaming. Because if you don't I'm not seeing why you'd need 12 cores. A 5600X or 5800X is going to be much better for games because of the higher per-thread performance than a 3900X.

And as always, the cheapest upgrade is no upgrade. If your CPU turns out to be good enough for the games you're playing why not just get a GPU and be done with it? It's not like CPUs are going to be worse or more expensive next year or in two years or whenever the time comes that you actually need to replace it.

EDIT: Your CPU would be enough for 80+ fps but even an RTX 3090 isn't going to get you 60 fps at 4K in AC:Valhalla. Well the 6900 XT will be a thing soon and you can obviously drop the settings a bit but I would strongly recommend you save some (or all) of the money for the CPU and put it towards a much better GPU.

80°C seems like a normal target temperature for a GPU. You can set it lower if you want to, but it will get louder and is unnecessary.

No issues.
Yes, for stock the stock cooler will obviously be good enough, overclocked it is indeed the easiest and potentially cheapest option to simply try and see.

That mobo will need a BIOS update to officially support that CPU but since it can be updated without a CPU or RAM installed that shouldn't be a problem.

Gigabyte also hasn't published the QVL (list of officially supported RAM kits) yet, but I'm fairly that RAM will work. If not since you can update the BIOS without having any installed when the new version to improve RAM compatibility is inevitably released that should also be fixable.

Even adjusting for clockrates that's about +30% for TF2 from Zen2 to Zen3, which is very nice.

#3739
Yes, though AMD will send you one on loan if you can provide proof of purchase for the CPU and mobo.
And like I said there are some mobos that can be updated without a CPU (see #3740) or you can simply buy one from 2020 (B550/X570) and CPUs from 2020 will work without any update.

The NH-D15 is just one examples and featured in many reviews, that's why I used it. No, 50°C while under load and overclocked is unrealistic for a 10600KF with either cooler. The 10600KF is much worse in that regard than the 4820K, but I also suspect that there wasn't that much load in games and you didn't overclock it very high. In a stress test it most likely would've gone up to 70°C and the 10600KF will probably reach 80 or higher and 60 during "normal" gaming loads. Either way the NH-D15 should be quieter at the same temperatures, though I haven't seen a direct comparison.

Yes, just checking so you don't pay for something you won't need.

You can check the timings on pcpartpicker. Basically marketing playing stupid games. Adverstise as "CL18", don't mention that the timings are 18-22-22-42, not 18-18-18-38 like you'd want them to be. Without changing the price range these would be better options:
https://au.pcpartpicker.com/product/ckvbt6/patriot-viper-steel-16-gb-2-x-8-gb-ddr4-3600-cl17-memory-pvs416g360c7k
https://au.pcpartpicker.com/product/2TFKHx/crucial-ballistix-16-gb-2-x-8-gb-ddr4-3600-memory-bl2k8g36c16u4b
Of course you can also go for the good stuff with 16-16-16-36 that is also better for a few other reasons but that's more like 180$ and not really worth it in your case.

What issues with updating the BIOS? Apart from the usual not being able to update the BIOS without a CPU, which should be obvious? You can also avoid that issue by buying a mobo from 2020 instead of 2019. Or buying one that can be updated without a CPU installed.

I don't like the cooler for the usual reasons.

Timings on that RAM really aren't great.

Do you need WiFi?

Yes, 10600KF would probably be enough.

HZD is probably just the shitty port, maybe your HDD.

Because the prices are what they are it's more like 250$ so I'm not sure what would be best.
For a new CPU you'd need a new mobo and RAM as well and that means 4 cores is doable, but not really worth it (used older CPU would get you half the benefit or more at a fraction of the cost), 6 cores is difficult and you'd have to get one with lower clockrate and that's not ideal for games so you'd be missing out on what a slightly more expensive upgrade would get you, high clocked 6 core is nice, but over budget and at that point you might be limited by your GPU again (especially in Cyberpunk 2077) so that doesn't really seem worth it either.
So those are your options. If you're not in a hurry wait for the 5600X because even if you don't want to go over budget like you'd need to to afford it it would at least push down the prices for older models.
