Question New PC Build Help

[hjud5258]

Hi

I'm working on a new build and have some questions.

Here's the build.

Custom AMD PC by Micro Center

Build your own custom PC with an AMD Ryzen processor. Award-winning performance and optimized technology for gamers, creators and business. Order online and have it professionally built by your local Micro Center.

www.microcenter.com

Here's some background on what I will be using the machine for.
I'm a full-time day trader and I put very heavy loads on my machine with multiple trading platforms, running other multiple programs, and a screen capture recording my screens during market hours. I’m a very heavy multitasker and put heavy loads on my machine. I will NOT be using this PC for any gaming. It’s strictly a work PC for heavy multitasking and day trading. The trading programs I use are Think or Swim, Scanz, Stocks To Trade, and Etrade Pro.

I was informed today by a tech at Think or Swim (one of the main trading platforms I use) to use this link below in choosing a graphic card. He said to choose from the upper blue/green area since the platform is very demanding. So I chose the GeForce RTX 2070 but not sure if I made the best choice.

https://www.eurogamer.net/articles/...27-gpu-power-ladder-all-graphics-cards-tested

Monitors I currently have:
Two Acer S271 HL monitors https://www.cnet.com/products/acer-s271hl-led-monitor-full-hd-1080p-27/
One 40 Inch MU6290 4K TV https://www.samsung.com/us/televisi...tvs/40-class-mu6290-4k-uhd-tv-un40mu6290fxza/.
I'm not currently using the MU6290 4K TV but may want to in the future. There's also slight possibility I may decided to get another MU6290 4K. If I do buy another one then the setup will be:
One Acer S271 HL monitor https://www.cnet.com/products/acer-s271hl-led-monitor-full-hd-1080p-27/
Two 40 Inch MU6290 4K TV https://www.samsung.com/us/televisi...tvs/40-class-mu6290-4k-uhd-tv-un40mu6290fxza/.

The questions I have are:

1. Processor: Is the AMD 3900 overkill for what I need and if it is does it make sense for the future?
2. Video Card: Is the GeForce RTX 2070 a good choice? Does it seem like overkill for my use?
3. Motherboard: Is the motherboard a good choice? I think it has wifi which I don't need but someone from another forum recommended it. I'm lost on this.
4. RAM: Does the 64GB of RAM make sense? Originally I was going to get 32GB but since Think or Swim is such a resource hog and it's recommended to put the settings to half your RAM. Theoretically it should only use what it needs. Are there any other benefits to having 64GB of RAM for my use?
5. GPU: I ordered the Seasonic 850 GPU today but received an email that it was out of stock so the order was replaced with Corsair RM850x 850 Watt 80 Plus Gold ATX Fully Modular Power Supply. Is that a good choice?
6. SSD Drive: I was told to get the NVMe M.2 drive for the main drive. I keep the bulk of my files on the D drive to keep the C drive clean basically with just programs and what's in my documents folder. That's why I chose two 500GB NVMe M.2 drives vs 1TB so that I could do that. Does this make sense and does it even matter anymore? In other words is there a benefit to doing this for performance or other reasons or should I just go with 1TB 500GB NVMe M.2 drive? Can I even have 2 NVMe M.2 drives? Will it affect anything performance wise?
7. Sata 3 Drives I chose 2 8TB Internal Drives for storage and backups. Will both these drives fit in the case and connect to the motherboard since I already have the two NVMe M.2 drives?
8. Case: Is this fractal design a good choice? Many recommended it.
9. Are the five P12 Fluid Dynamic Bearing 120mm Case Fans a good choice?
10. Is the Reaver CC-1101 CPU Cooler a good choice? Is this a good idea to have?
11. Any other thoughts or recommendations?
If you've gotten this far you're probably exhausted so thanks so much for taking the time to read it. This build is very important to me since I daytrade for a living and I also need a powerful machine for all the multitasking I do.

My opinion, for what it is worth:

1) A Ryzen 7 would probably be a good use case for your system, and you could probably get by with just a R5 3600 just fine. Then again, there isn't anything wrong with going with the 3900x either as you'd just be future-proofing against having to upgrade.

2) In my opinion it is supreme overkill. A consumer GTX-1650 would run a 4k TV as a monitor just fine, as would an RX-5600XT as long as you make sure the card you choose (either brand) has enough outputs. Were it me I'd go with something like a Quadro K1200 workstation card because stability is the absolutely most important thing for that use case. If you do this, though, none of your monitors have displayport ports so you'd need displayport to HDMI adapters. You also didn't mention how many of those monitors you plan to use.

3) There is no motherboard shown in the proposed build link.
EDIT: it is showing now, where it wasn't earlier. Weird. Anyway, there is nothing wrong with the board choice.

4) You can always try 32GB and upgrade if you feel that it isn't giving you the performance you need. Memory is only going to get cheaper over the next 6 months as there is presently a DRAM supply glut.

5) PSU is fine, though 850 watts is kind of overkill (especially if you go with a lower power video card). However, given the shortages, you take what you can get and Corsair is generally a very good PSU brand.

6) There is nothing wrong with what you are describing doing. Yes, you can have more than one NVMe drive if the motherboard has multiple m.2 slots (or if it doesn't, you can buy a cheapo NVMe m.2 to x4 PCIe adapter that will work great). NVMe drives will be dropping in price over the next 6 months due to a flash memory supply glut.

7) Yes they will fit. However, if this system is your livelihood, you need an external backup (either encrypted cloud based, or at least a pair of smaller USB hard drives so you can alternate backups with at least one stored outside of your residence at all times - especially if you are maintaining electronic records). Putting all your backup drives in the same system is like kicking Murphy in the cojones with steel toed boots, laughing at him, and just daring him to ruin your life. In short, don't do it.

8) Cases are a personal decision. There is nothing wrong with Fractal Design as a brand - they make some really nice cases. Most important thing is to make sure that the case you choose has the ports you want in an easily accessible area.

9) P12 fans are fine. However, you might want to get the PWM version so you can hook them to a fan controller to slow down and quiet the fans as needed.

10) With a mid-ATX size case, there is no reason to limit yourself to a small cooler. I always recommend Noctua as their hardware and support are absolutely top-notch. The U12S is nice, it isn't as large as the D14 series, but will be reusable even with high end CPUs.

11) Windows 10 Home as an OS has one limitation - the inability to delay potentially problematic updates beyond 30 days. Windows 10 Pro allows you to delay updates up to 365 days.

Also, since day trading is your livelihood, do you have a backup system available to enable you to continue trading in the event of a catastrophic system failure?

You most likely don't need a 2070.

I would recommend going with an x570 motherboard if you're going to be running 2x Samsung 970. Fyi, the B550 aorus pro uses the pcie x4 electrical slot bandwidth for the 2nd m2 drive, so that slot is inactivated. If you have more than 2 SATA devices, the 3rd x16 slot also inactivates. Not a problem if you don't need any additional pci-e cards though.

I would also recommend PRO, since home has a MAX memory limit of 64128GB, so there would be no way to upgrade it in the future if you needed more hah.
windows 10 pro also allows sandboxing of programs, which is nifty.

windows 10 pro also allows sandboxing of programs, which is nifty.

Memory limit for Win10 Home x64 is actually 128GB, but I do agree with the Win10 Pro recommendation. I didn't even think about the sandboxing feature, so that is a plus.

Great tips above. I would absolutely recommend using one nVME over two if you end up with the same capacity (eg single 1TB vs 2 500GB models).

SSDs increase in performance by size, and decrease in performance when they get closer to full. So a 1TB Evo will outperform the 500GB Evo.

You can manually map the various profile folders to other locations easily (desktop, documents, downloads, music, pictures, and video folders). I usually do this for people with smaller SSDs. For you I'd probably recommend a mix, setting only download, music, and video to remap to D:\Profile\etc for example. This means anything that goes into those folders doesn't have to be manually moved off your SSD after the fact, it's just seamless. But your documents and any desktop items you're working with are stored on the SSD for max performance. Less PCIe chatter with a single fast nVME is also preferable to multiple drives if you don't need to. And leaving open nVME slots is optimal for later expansions.

Agree that cooler is also underpowered for a 3900. Ryzens are efficient, but they run best when kept cooler, so a big Noctua in the 140mm single/dual fan selection is ideal.

Thank you for all this info. I appreciate it. I went to work on it and updated with your suggestions.

I ended up keeping the 64gb of RAM just in case since I was able to find it in 2 sticks of 32gb which was discounted and someone said its better to have 2 sticks then 4 sticks. Is that true?

I went with 1TB NVMe drive to make it cleaner.

I upgraded to Windows Pro.

I'm with you on the backups. I have current externals and I have Crash Plan as well.

I can get the NH-U14S CPU Cooler from Amazon since microcenter doesn't have either NH-U14S or NH-U14S in stock. https://www.amazon.com/gp/product/B00C9FLSLY/ref=ox_sc_act_title_1?smid=A1Z5H6ZGWCMTNX&psc=1

Thank you I took your advice and confirmation and made changes to 1 TB drive and Windows Pro. Sandbox looks cool.

Here's the new build https://www.microcenter.com/site/co...spx?load=8cf23dcc-c48e-4c2b-b935-3edaa7db08d0 less the Noctua NH-U14S which I'll order fom Amazon.

 

[Arkaign]

Weird thing with Ram. 4 sticks is faster (check Hardware Unboxed on this), but that also leaves you with no open spots for upgrade. The performance difference is not that big, but I find it interesting for a dual channel architecture.

Are More RAM Modules Better for Gaming? 4 x 4GB vs. 2 x 8GB

You never did say how many monitors you were planning to use. Make sure the video card you choose supports the number of monitors you plan to use, and also that it has has enough of the right type of output ports to support the monitors you already have.

Oh that's a good question. I took the specs off of a custom trading computer site and I think I got the correct one for my use. I hope I did.

4 Monitor Support - 3x HDMI, 1x DisplayPort (GIGABYTE GeForce GTX 1650 Windforce OC 4GB GDDR5)

I'm going to currently use the setup below for a total of 3 monitors.

Two Acer S271 HL monitors https://www.cnet.com/products/acer-s271hl-led-monitor-full-hd-1080p-27/

One 40 Inch MU6290 4K TV https://www.samsung.com/us/televisi...tvs/40-class-mu6290-4k-uhd-tv-un40mu6290fxza/.

As far as the cables go I'm using HDMI on both of my Acers now but they have the micro end of the cable going into the current video card. I also have a bunch of regular size HDMI cables that are normal size so if I'm looking at this correctly I should be good with the 3 monitors and the regular HDMI cables I have.

If I ever get another 4k then I will have one Acer in the middle and 2 4ks on the each side which to me looks like that will work with this card too but I'm not sure if an extra 4k would cause issues with that card.

That is interesting. I just read that. So I guess since it's not much of a difference and never really knowing how much in my case it makes sense to stick with 2 sticks so that if I ever want to add more memory it's less expensive. (even though I can't imagine I would need anymore)

 

[Steltek]

4 Monitor Support - 3x HDMI, 1x DisplayPort (GIGABYTE GeForce GTX 1650 Windforce OC 4GB GDDR5)

That is correct according to the Gigabyte support site, so the card should support 3 monitors with HDMI. In a pinch if you ever need to, you can get an adapter to convert the Displayport output to add a 4th (or, add a Displayport monitor).

Beautiful. Thanks for the confirmation.

Be aware that your chosen memory isn't shown as compatible on either the motherboard QVL list or the g.skill support site. That doesn't mean it won't work, but just that it hasn't been tested yet and shown to be compatible in that configuration.

Unfortunately, you will probably find that to be the case with most 2x32GB module configurations on anything outside a pure true workstation motherboard (i.e. a Threadripper/Xeon board that supports hundreds of gigabytes of memory).

Oh thanks so much for looking into that for me. It's interesting because when I went to select it and added it an incompatible message came up so I refreshed the page and it went away. So I thought it was just a glitch but apparently not. I'm surprised it went away. So now I'm thinking it's probably better to be safe to go back to the 4x16gb. You think that's a better idea? I can't imagine I would need more than 64gb.

It depends upon how you are getting the memory. If you are walking in to Microcenter to purchase and pick up everything, you can always try it and return it if it doesn't work.

g.skill does sell a pair of Ripjaws 2x32 kits known compatible with that motherboard, just lower clocked at DDR4 2666 and DDR4 3200 (which is why I suspect the modules you selected might work).

If it was my system, I think I'd probably risk it as long as I was in the situation where I could quickly return/replace the memory.

Oh ok that gives a little bit of insight. I'm actually going to have Microcenter build the entire machine and install Windows so I guess that will be the test if it works or not. This brings up a few more questions I guess...

Is this the type of thing that it either works or not immediately or could it fail down the road?

Could it cause any damage to the machine using it that way assuming it works?

If it doesn't work do you think its better to just go with the 4x16gb for the higher clock speed?

It won't be anything that will damage anything. It will either work, or it won't. If it doesn't, you just have them switch it out for something that will work. Their own system is showing it as compatible, so it shouldn't be a big deal and they should warrant it if they hand it off to you. I really wouldn't expect a problem.

BTW, they'll probably have the Noctua CPU cooler in the store (Noctua is a major enthusiast air cooler brand) even if their "compatibility tool" isn't providing it as a choice. They will have to have the CPU cooler to build and boot the system, so you need to discuss how this will work if you are buying the cooler from Amazon. They will probably want you to buy it from them if you want them to warrant the work - ask them if they will pricematch Amazon on it. Just talk with one of their techs, tell them what you want, and they shouldn't give you a problem.

oh perfect. Then it totally makes sense to let them install it and see how it goes.

I went ahead and ordered the Noctua CPU from Amazon for overnight delivery because on the Microcenter website it shows as sold out in every store and the webstore. the NH-U12S isn't available in my store either. So I figured better to just overnight it and have it sometime tomorrow and possibly have this built over the weekend.

I can't even believe I'm almost there. This has been going on a 2 week project. I learned a lot and probably could have just got anything and it would have been an upgrade but I wanted to take the time to get what was going to be most beneficial to my needs, especially since it's been 6 years working on this machine. I really appreciate all your help.

 

[Steltek]

One final thing. Because you will use this for purposes of your livelihood, I'd suggest that you purchase a decent sine wave UPS for it as soon as you can afford it. Consider it insurance for your new computer investment.

Good luck with everything, and post back if you have any problems.

Thank you for this suggestion. I didn't even know what sine wave was. I have this right now https://www.apc.com/shop/us/en/products/P-BN900M which I bought in 2018 and then it was replaced under warranty after it failed last year right after a storm. I've moved since to a newer complex and never have issues with power but there are storms that come around here in Dallas.

I did some research on what sine wave is and from what I can tell this doesn't have the sine wave that you're referring to. Am I correct about that?
Waveform type
Stepped approximation to a sinewave

Is there one that would recommend or what to look for?

 

[fralexandr]

They used to be advertised as True/Pure Sine Wave, but now Cyberpower advertizes it as PFC Sinewave, and APC advertizes it as Sinewave UPS designed for high-end electronics.

From a quick search, the cyberpower 600W is currently cheaper than the APC variant, whereas the APC 810W and 1000w are currently cheaper than the cyberpower variant.
