Suggestions for a new PC

[Ozymandias]

Timing is important.
If you wait for a major CPU release, all the progenitor CPUs will drop, sometimes significantly.
A big PSU is a really good idea if you plan to upgrade. I have 1400 watts. Sounds like a ludicrous total, but 280W for the CPU and about the same for 2 GPUs gives nearly 900 watts even before you power the motherboard, ram, disks, peripherals, etc. I figure it is barely adequate.
Besides water cooling, I have a 12 amp commercial blower I use to blast air through the case.

You can always add GPUs later. Besides, for now, the CPU version of SF is nice and strong.
Another thing to remember is that time is also power.
I have a 32 core 64 thread AMD. I could have spent a lot more and got the 64 core model, but if I run for 1.75 times as long, I will get the same analysis.
I have lots of other mighty machines but I only run them when I need to because they are old technology and gobble down power with a slurp and a burp. When I have the whole gang of machines going full tilt, I get up to 700 dollar power bills.

You mean 12cm 12V fan, coz 12A, i.e. 150W fan in 120mm would be like having 100k+ RPM (i.e. would sound like a helicopter) .

With that much wasted electricity (I understand it's a hobby but your CO2 footprint is horrible) you should really consider some solar panels (like a football field of it) to offset the impact on global warming you are making .

Guilty as charged.

For me, it is not a hobby. It is an illness.
No, I really mean it.

He forgot to mention the tons of potatoes you could buy instead.

That blower setup must be among the most ugly things I've seen. I have to get some soap behind my eyeballs now, for slow and lengthy release.

Thanks to everybody for your suggestions. I'll do some research about those options.

I am guessing you're planning to use it a lot, otherwise you could use Google Compute Engine until GPU prices fall.

Not really and for what I am reading, Rasmus and John suggestions are closer to what I need. I did not know about Google Compute Engine.

Google Compute Engine is a service for running computationally intensive tasks in the cloud. Last time I checked (probably a year or so ago), their prices for renting powerful processor and GPU combinations were very competitive. Here's the current pricing - link. IIRC you get some free "compute units" when you start your account, so you won't even have to start paying immediately. If you don't know for sure how much you're going to use your new computer yet, you could possibly do your heavy computing in the cloud until you have a better idea.

A100 is the only one that makes some sense with respect to GPUs (performance/price). Still for any really intensive task (like training) not just from time to time analysis this would be quite a costly option. You run in 24/7 for tree weeks and it would cost as MSRP of RTX 3090 (which is almost on par with A100 in terms of performance).

Are you sure Ryzen 3700x is 12 cores? I can only find the one with 8 cores. The cheapest in my country costs $ 396.

I meant 3900x. That is 12 cores. But the 3700x is also a reasonable choice.

Hi, How many games do you think can be played simultaneously without a problem on an R9-3900 (12 cores 24 threads)?

I see, the Ryzen 9 3900x costs $596 here.

What do you guys think between the 3700x and the 3900x? With the other PC parts would the 3900x be within the budget?

The 3700X and 3900X are nice, but don't have integrated graphics and thus require a GPU - which throws you back to square one. I'd take a look at Ebay to get a 4750G.

I bought a watch from eBay and took like 2 months to get here, plus now I am not in the capital, so it would take longer.

What would be a good (for YouTube, 4k videos, I don't play other games besides chess and variants except Diablo II) and cheap gpu for the 3700x?

good and cheap gpu?

Even previous generations have skyrocketed. What you can get for around 90 EUR would be Nvidia GT 1030 - a 30W part about on a par with the integrated graphics of the 4750G. For 190 EUR, you can get Nvidia GTX 1650 with 75W which is 3.5 times as fast, i.e. better but still in the low end. Or a slightly slower GTX 1050 at about the same price.

The point would be to have any sort of even outdated graphics with a CPU that doesn't have integrated graphics, and then wait until the Ethereum crypto currency bubble bursts. At that point, the market will be flooded with cheap and good graphics cards. If you plan to go Nvidia long-term because of LC0, I'd probably take the GT 1030 now.

For reference, the GT 1030 is not only on a par with the 4750g graphics, but also with the 3400G graphics, and that's the CPU I have. This is able to play Flare under Linux. Flare is a Diablo II like open source game.

4k videos should also be fine to watch, but if you refer to Netflix specifically, the graphics card needs to have 3 GB RAM minimum due to the DRM. The GT 1030 has only 2 GB, so that's out for Netflix. In that case, the GTX 1650 (or 1050) with 4 GB (pay attention when buying) would be the way to go.

Thank you for the very detailed explanation. Diablo II does not require much graphic power. I can play it on my old (2011) i3 Lenovo laptop.
I don't use the PC for Netflix, but might be a future possibility.
What would be another option with integrated graphics besides the 4750G?

What would be another option with integrated graphics besides the 4750G?

None with 8 cores. The 4650G with 6C/12T, the 4350G with 4C/8T, and the older 3400G with 4C/8T. I mean, you could get an Intel Core i9-9900K that has integrated graphics, but it's from 2018, the UHD 630 graphics are really meh, the multicore performance is worse than 4750G, and the pricing isn't attractive, either.

As it stands, the most economic option if you can do without Netflix in 4k for the moment would be the cheap GT 1030 GPU and a Ryzen 3000 or 5000, and then replacing the GPU once Ethereum collapses. That way, you could keep most of the system. Also, when this collapse happens and GPUs are on the market, I expect tons of gamers to buy new PCs because all what keeps them from doing that right now are the GPU prices. This in turn might make CPUs scarce.

Another option, but not for right now, would be the 5700G which has not yet been released, but benchmarks with engineering samples have leaked. If the rumors are true, that would be a successor to the 4750G, but with Zen3 architecture like other Ryzen 5000. The release is expected in the first half of 2021, and the price is rumored to hover around $350.
