Hey thanks in advance guys. I am a full time day trader and I am building a computer for running scans and accessing lots of data throughout the day for 4-8 ish hours at a time. I read something about processor cores basically being useless if there you don't have other components to access all the cores properly. I want to make sure that I am getting the most out of my cpu for the most efficient trading needs. Its no gaming, but still very data-intensive. If you can help with guiding me it would be awesome and really appreciated because I don't know much about computers. I will also be running 2-3 Dell 27 inch 4k Ultrasharp monitors, so I want to make sure my graphics card can efficiently run those. Thanks ! Also, any other suggestions about making my desktop badass and fast with all this is appreciated.

A very good start.

1. I think GTX1060 is appropriate.
Buy an EVGA version. In the event that you find you want something stronger, you can return it within 90days and get credit on a stronger card. A good option that I do not expect you to need.
The one I linked can hold 3 dp connected monitors as well as a 4th via hdmi.

2. The psu you need is gated by the graphics card you use. A GTX1060 needs only a 450w psu.
Even the strongest cards will do fine with 650w.
Here is a chart :

Of more importance is the quality of the psu.

Corsair HX is good quality, but 1000w is way overkill.
I might suggest this Seasonic focus 650w unit.
gold rated, modular, 10 year warranty...

start from checking task manager on how much your app is using the CPU, you worry about stuff that should be solved on program or CONFIG level.
Just to make it clear if program you use DON'T support multi-threading then you cannot do anything except running few of them in parallel (which might break other things so in general not best idea). I am almost sure that your "trading" program will use whatever you have. Just double check that.
About GPU, dont worry, integrated GPU should handle one monitor and you will need 1030 GPU for another 2 screens

as for other parts, get any gaming guide and replace GPU for cheaper one ;)

Can you list all of your proposed parts?

From the CPU point of view, you probably need do nothing.
The 8700K at stock is a beast.
The processor power can be increased perhaps 20% via overclocking, but you need not do that initially.
To allow for that, use a very good cpu cooler like the Noctua NH-D15s.

To attach 3 monitors, you will need a modern graphics card.
Your images will be relatively static, so you do not need a powerful card like might be used for gaming.
Look for a card with three displayport connections like this evga GTX1060sc:

From the overall performance point of view, a ssd is essential.
Plan on putting everything on a single large SSD.
If needed, a HDD is ok for backup.
Samsung evo is the best at a reasonable price. Only intel optane is faster, but it is new and pricey; probably not a good thing.

The task manager things is awesome! it looks like my first platform uses up to 19% of my CPU at the highs and uses the GPU up to 40%. I am not exactly sure how to interpret this
when i open the second platform simulaneously, the second platform uses no more than 4% of CPU and no more than 7% of GPU. lmao the second platform seems a lot more efficient. the first one is in its early stages of development still.

Also, this is all on my dell xps and here are the specs
CPU: Core i7-6700 HQ CPU @ 2.6 GHz
GPU: NVIDIA GeForce GTX 960 M
16 gb of ram

3. I7-8700K is as good as it gets.
stock clock is 3.7 with a turbo up to 4.7
Most will overclock all cores to 4.9.
If price is no object, you can buy a better binned 8700K from silicon lottery that can do 5.2:
https://siliconlottery.com/collections/coffeelake/products/8700k52g

4. You will need a Z370 based motherboard. All are good.

5. You need sufficient ram to hold the contents of all your apps.
Normally, a 2 x 8gb ddr4 kit will do the job, but, I think you would be safest with a 2 x 16gb kit up front.
Speed is not important, something like 3000 to 3600 would be right.

6. A z370 motherboard will hold a m.2 pcie ssd device. A 500gb Samsung 960 evo will have better sequential speeds than a simple sata ssd,
Samsung tends to be a touch faster and be more reliable today.

7. A case mainly needs to hold your parts.
I like one with two front 120/140mm intakes which are filtered.
That will keep your parts cleaner.
Pick one that looks good to you.

Wow this is all very helpful stuff. I was thinking about a case like this http://bit.ly/2FLYv6d however I need help with size to be sure it will fit everything. About keeping the parts cleaner, is the 120/140 just the size of the fan?

A very good looking case which will do the job for you.
(I am not a fan of bling though)
The 120/140 mm refers to the fan diameter.
140mm fans turn slower but push more air than 120mm and are quieter.
Since the case comes with two 120mm rgb fans, you need do nothing.
The cooling capability of 3 120mm fans will be about the same as 2 140mm fans.


I might add a single 120mm fan at the rear to direct the airflow through the case; nothing stronger, otherwise unfiltered air will be drawn in from adjacent openings.

The case will hold any normal ATX sized motherboard you want up to 272mm long.
Some eatx motherboards are long, but a normal ATX motherboard will be about 250mm.

https://www.newegg.com/Product/Product.aspx?Item=N82E16813119038 I was thinking this motherboard. I want to basically have purple lights only in accents. With RGB you can have it stay on the same purple color only right?

Updating/refreshing a few fields of HTML for updating stock prices is hardly a 'Cinebench' sort of load for even an old i3, much less an 8700K...; your internet connection will be the bottleneck anyway, so the 1 billionth of a second screen update time differences won't make much difference unless you are pretty darn fingered on short sales! :)

its not just the prices, its streaming every single trade coming through on every ticker I am watching, as well as constant updates on the charts. There's usually about <10 tickers and charts im watching. Plus the application I use is still in early development stages so it hogs a lot of the CPU and GPU power. I just want to be sure that it can handle whatever I have pulled up. What kind of of CPU would you reccommend

Agree with Geofelt, the 8700k is a very good cpu and it will last you quiet some time based on your use case, especially if MONEY is not a key issue. From the AMD camp and if you want to save a few pennies, then the Ryzen 1700 will also do a great job especially as gaming is not a factor and you get 2 more cores and 4 more threads. Worth thinking about though I have the 8700K and can only sing it's praises!

The power supply is overkill and as Geofelt says a good 650w supply would be perfect...One of the best is the Seasonic Prime Platinum 650w...

mdd1963 has a point as the internet connection will be key and what you are looking at is fairly powerful for what you need...but as I always say, if you can afford it get the best you can at the time of purchase as it will last you much longer.

An 8700K, z370 mid range motherboard like the Gigabyte Z370p D3 (cheap) or the ASrock z370 Pro4 (also very cost effective) or for a bit more than the MSI Gaming Carbon Pro, Asus Hero or Gigabyte Gaming 5 or 7 will all be more than good enough. 16GB Ram Corsair VENGEANCE LPX 16GB (2X8GB) DDR4 2666MHZ dual channel kit..you can maybe get something cheaper, but these are very good and fairly cost effective and you are good to go with a GTX 1060..
