Yeah, I'm not sure about that. The mobo should not be at 60 and the CPU that actually generates the heat should not be at the same temperature as the mobo.
For comparision: Even if I push the CPU above 70 with benchmarks the mobo doesn't even get to 30. So I'm not sure which sensors you are reading or what kind of abomination your cooling setup is.

The chipset doesn't affect performance. DDR3 isn't ideal though.

Most likely thermal throttling, it's mini-ITX after all.

Try the GPU in a different pc or a different GPU in your pc or both.
If you're really bored reinstall windows.

Not really a build question though.

The score seems perfectly normal. You can check the clocks in Afterburner but it doesn't seem to be throttling.

Well the 96% seem fine then.
Does it run cooler on actual benchmarks like Unigine Heaven/Valley or whatever?
If the noise isn't bothering you you can leave it as is. If you've got thermal paste lying around you could repaste it but it doesn't seem necessary.

What custom fan profile did you set? 82°C is the default temperature target iirc so the fan is probably spinning up to keep it there.
Furmark isn't exactly a normal load and a GPU with the same cooler but 50% higher TDP will run hotter. If it can handle the absolute worst case like Furmark while (barely) keeping the target temperature it should be absolutely fine under normal load.
It's a used GPU but less than 2 years old so don't expect any miracles from repasting. You're not going get 70°C with that cooler while burning 300W.

Timings tend to be suboptimal. I mean if it needs 1.35V to get to 3200CL16 it's not going to be that great with 1.2V at 2666.
If he's streaming it's not pure gaming. Also generalizing this to a "Intel always outperforms AMD" in games is wrong. You're forgetting that this isn't the usual comparision of 9900K vs 3900X with >3000 MHz RAM for both that everyone has done. Sure, that's a 5-6% difference on average, but this would be 3600(X)/3700X vs 9700(F). PBO/AutoOC will still push the 3600/3700X to about the same clocks as the 3900X. Sure, they all struggle to reach the 4.6 GHz that the 3900X should nominally get, but the point is that they all get extremely similar clocks and single threaded performance. Not ideal for AMD, good for their customers. On the other side the 9700(F) will absolutely not run at 5.0 because it's only rated for 4.7. That's already more than 5% gone. Add the lower TDP and baseclock and it will definitely lose on average. Sure it'll still win in some games, but so does a 3900X against a 9900K and you wouldn't say that that one is faster either. Then you realize that it won't be the same RAM, rather 3200 for the 3700X vs 2666 for the 9700(F) and it's really not salvageable anymore.
If you want to complain about the price difference compare the 9700 and 3600(X). 6c/12t isn't going to lose to 8c//8t in multithreaded workloads either.

EDIT: Don't forget that the jcc fix costs another 0-4% according to Intel (and Intel will always use rather optimistic numbers) so all Skylake/Coffee Lake benchmarks would have to be redone to get the current performance.

NVENC vs x264 isn't that simple either. Sure, OBS/Twitch can't use better encoders like x265, VP9 or AV1, but it doesn't support Turing HEVC or even H264-slow either (although OBS is slowly catching up). Turing NVENC still wins against x264 at 1440p or 4K or at presets like faster or veryfast. But 1080p? Things are a bit different. And on an 8 core you're really not going to use veryfast.
Not a clear win for either side. No CPU load is quite nice so that's a point for GPU encoding, but on the other hand as soon as x264/H264 isn't the only choice anymore the balance shifts in favour of CPUs again. Can't update hardware encoding after all. This would be easy if high CPU load wasn't tolerable or a lot of cores were important for another workload, but the way it is he doesn't "have to" choose GPU or CPU encoding, both would work.

Other than selling the old build I see no reason to replace the PSU and HDD at all. You could get a new case if you want one, but it's not necessary either.
The PSU should still last a few years minimum. The HDD is going to die eventually, but if you do have backups it doesn't matter and if you don't you're just playing the odds and hoping that you don't get fucked because any HDD could die at any time (more likely when it's brand new and then again increasingly likely as it gets old).

To get you from 90 to 100+ fps won't require overclocking at all so we can skip that as well.
A GPU upgrade should be quite easy as well. Even an RX 560 or GTX 1050 is faster than a 7850 and a GTX 760 loses to 1050 Ti and is hopelessly outclassed by an RX 570, neither of which are particularly expensive.

The partial build is all over the place. New cooler (not a great one at that and virtually identical to the one you already got) and Z390 mobo (most expensive, but allows overclocking and >2666 MHz RAM) but a locked CPU and 2666 MHz RAM? So yeah, don't get that. Either overclocking all the way or none of the way.

1000$ should be more than enough. It's mostly about the balance you want and if you're going to keep anything or start from scratch.
You can easily get a 3700X, 5700 XT and a nice 1 TB NVMe SSD.

Of course if you don't think you'll need 8 cores / 16 threads because even a bit less would be quite an improvement for streaming you can do that and drop down to 6 cores to get a new case/PSU or a better GPU. The opposite is possible as well. If you want 12 cores you can get them, but you'd have to get a GPU that's only twice as fast as your current one instead of 4-5 times as fast. Or 6 cores and 3x GPU performance to save some money because that's still a huge upgrade? The choice is yours.

#3469
B365 only supports 2666 MHz RAM.

#3470
This guy speaks the truth.

#3471
Not guaranteed if it's old stock.
I like the Tomahawk too but went with the Gaming Plus because being able to update the BIOS without a CPU just in case is the safer option.

The other can games can be pretty hard as in hard to get the framerates you want?

How many fps are you getting and how many would you like? That should give you an idea of how much of an upgrade you need.
Price to performance ratio generally only gets worse above ~200$ so it's better to get a GPU that does what you want and not much more and then upgrade again in a couple of years.

Yes.

That lawsuit is about a different issue though. An FX-6350 isn't any better, the cores are still garbage, but you can't sue AMD for that. You can however sue AMD for advertising the 4 module/8 thread SKUs as "8 core CPU" if you're salty that a 200$ 4 module/8 thread AMD CPU not only doesn't beat a 2000$ 8 core/16 thread Intel CPU but even loses to a 300$ 4 core/8 thread Intel CPU. Who would've thought...

In case you're wondering where your CPU ranks (for games at least) and what would be an upgrade:
https://cpu.userbenchmark.com/Compare/AMD-FX-8350-vs-Intel-Pentium-Gold-G5400/1489vsm484278
Literally anything.
If you go dumpster diving and find an old office pc with a 5 year i3 it's probably not going to be any worse.
So that's the good news, you might be able to get a very cheap or even free upgrade if you're willing to look and/or ask people.

Seems normal tbh.
More than 3/4 threads really don't do anything for TF2.
You could try pinning to the same/different modules just to see what happens.
Probably won't do much because your CPU is shit.

Long responses are better than incomplete responses that require 3 rounds of followup questions.

For anything but TF2 I don't think CPU overclocking would really be necessary. It's not just the CPU, it's also the mobo (Z instead of B/H) and usually the cooler although not in your case. It adds up to 50-100 quid depending on the CPU price difference and mobo, which is a bit much if you're not going to use what you paid for. If you're not going to OC a 3700X might actually be faster in addition to being cheaper. Or even a 3600X. 8 cores without SMT vs 6 cores with SMT isn't necessarily a win for the 8 cores.

Yes. You should definitely consider it for the next monitor upgrade though.

Price to performance ratio always gets worse the higher you go. It's a matter of needing/wanting that much performance.
No blower/reference design (single fan), none of the crazy super expensive super high factory oc ones either. Decent cooler, a bit of factory oc are usually the most reasonable choices. You'll have to read reviews, ideally roundups, to compare the coolers. Even if you don't care about the noise GPUs with nominally the same clockspeeds and a different cooler can end up performing significantly different.

Well the temps at 15% load don't mean shit. Any decent dual tower (and I assume it is if you didn't overpay massively) will do fine though. If they fans didn't break they're fine.

Mobo doesn't matter too much for the GPU. I mean PCIe 4.0 is coming, but so far only X570 offers that which is both AMD and quite pricy. No PCIe 4.0 for Intel consumer CPUs before 2021 afaik. Either way that's a 1-2% difference and beyond that the GPU can't even tell mobos apart.
More important would be the decision between Z (overclocking) and B/H (no oc) or even AMD, which all depend on the CPU.

Well first of all: Overclocking yes or no?

Secondly, 144 fps at 1080p max settings in any game really isn't going to happen. In some sure. Near-max in a few. But a stock RTX 2080 doesn't quite get 144 average in Witcher 3 and that's a game from 2015. Aftermarket or 2080 Super sure, but just moving on to a 2016 game, Deus Ex: Mankind divided, even a 2080 Ti can't save you anymore. Of course on the other hand something like Wolfenstein II will happily run at 250/300 fps even though it is even more recent. So it really depends on the game. And how much you're willing to drop down from max settings. I doubt Cyberpunk 2077 is going to be any easier to run than Witcher 3, but at high, not max? Might be doable.
You could also look into G-Sync/FreeSync. Barely getting 150 avg and dropping to 120 frequently isn't going to look great. With variable refresh rate you don't care that much if it fluctuates between 100 and 144 with an average of 120 or between 130 and 144 with 140 average.

Case and PSU should be fine. Which CPU cooler exactly?

No, the "AIO cooler" thing should never be something worth considering. https://www.teamfortress.tv/12714/pc-build-thread/?page=19#556

Could do better on the RAM and SSD, but that's fine tuning best left for later.

At that budget the price to performance ratio will only get worse, not sure if you consider that overpaying.
Maybe check whether you'd get 120 fps in recent games on the settings you want.
Short of waiting for Zen3 there isn't a whole lot you can do on the CPU side. If anything since streaming isn't a priority you'd be fine with fewer threads/cores (9700K/9600K), but that might not even be an upgrade anymore depending on what you've got right now. Maybe the 9900KS if it is in stock and not too expensive, but the difference between that and a normal 9900K(F) is probably marginal if both are overclocked.

PSU is fine. Fully modular is a bit nicer to build with, but I see no reason to replace it if it isn't that old.

Flashing is fairly easy if you've got a working CPU so yeah, definitely try it.

#3460
Well do you want it to be faster or cheaper?
7200 rpm HDD and 2070 Super are definitely things to consider, otherwise it looks fine.

120 fps on high for a few years might be a bit overoptimistic but replacing the GPU is easy.

#3461
Source? And there is a wrong answer.
