This is an Alienware pre-built? What are you using this for? Video editing / rendering or just gaming and streaming?

iamacow · Mar 15, 2018

If its the same price I would buy 2 1080 and mine with them. you will ROI much quicker.

faalin · Mar 15, 2018

I hope you're not paying that amount for the system as i just built it on dell for a tune of $7k, and that only had 1 1080 watercooled, didnt see an option for 2.

https://pcpartpicker.com/list/KKmQV6 $1k cheaper and i basically picked the most expensive parts i could, so their is still room to trim some fat off it.

zionyt27 · Mar 15, 2018

Lucky_SLS :

yes this is an alienware pre-built, and im using it for editing and rendering like cinema4d, adobe premiere pro, sony vegas etc. i will also be doing streaming / gaming with games like rainbow six siege, rust, pubg, fortnite, etc.

zionyt27 · Mar 15, 2018

faalin :

Ok, I'll look into it. Thanks!

zionyt27 · Mar 15, 2018

faalin :

Oh and yeah, when I chose the parts on dell there was an option for 2 now that I checked its gone, so I'll probably just do the one you linked me to.

Mount the Enermax aio in the the top with the ML 140 rgb fans.

Put one gpu rad in front(the top most gpu) and the other in the bottom.

Fill up all the fan slots. Have the top aio as intake. The gpu rads should also be intakes. Put the rest as exhaust.

Raid 0 those 3tb baddies for fast loading

For the rear fan if you so wish : https://www.google.co.in/url?sa=t&source=web&rct=j&url=https://m.newegg.com/products/N82E16811984011&ved=2ahUKEwi01Y_jtu7ZAhWCw7wKHZizBicQFjACegQIARAB&usg=AOvVaw1QZAUIDiO-YKG_e-lJqt8K

there is no point in multi GPU.
It adds input lag and stability issues with no clear future as SLI and CF are deprecated with DX12/Vulcan. Developers are too lazy (and greedy) to implement multi GPU support unless it is sponsored by GPU vendor. Single high end GPU is better life than 2 lesser GPUs.
So even if you have to spend the money, a 2TB SSD instead of second card would be more useful.

Lucky_SLS · Mar 15, 2018

^ he said he was doing heavy video editing/ rendering. That's y the sli.

If it's just gaming, then the 7980xe would be putting ten shots in ur brain n then burying it(fancy way of saying overkill...)

n0ns3ns3 · Mar 15, 2018

OMG there is an almost 2 seconds difference between single and dual GPU !!!
You are absolutely correct !!! everyone must pay for that well over a thousand (card, PSU, cooling and power bill).
https://www.techspot.com/article/1270-premiere-pro-cpu-gpu-performance/page2.html

But wait, Cinema 4D can't use multi GPU - another good reason to buy 4 of them.
http://support.nextlimit.com/display/RFC4D2/GPU-Acceleration

and the vegas ...
VEGAS does not benefit much (or at all) from NVIDIA SLI or AMD CrossFire.
https://www.vegascreativesoftware.info/us/forum/faq-graphics-cards-gpu-acceleration-for-vegas-pro--104614/

let's recommend to buy a VR ready RGB GAMING X dust filter otherwise the power led will bottleneck the mouse and the system will explode.

Lucky_SLS · Mar 16, 2018

I think u got confused reading those data

Let me highlight it here : from
http://support.nextlimit.com/plugins/servlet/mobile#content/view/39827118
" We have observed that the number of GPU cores makes the difference. As a simple rule we can say: the more GPU cores, the better."

So with sli, ur vram remains the same, 11gb. But ur Cuda cores doubles. So makes sense I guess?

Oh, n not to mention the cpu bottleneck. That was a broadwell 10 core vs 16/18 core cpu we are talking about, a 175-200% performance increase.

Moreover, I didn't recommend a 1080ti sli, I just suggested that the op had the option to go sli. I don't know the op's work tasks, how much he renders, adds effects etc, etc,. Just seems u got a bit salty...

n0ns3ns3 · Mar 16, 2018

Is is that hard just to read few more lines ?

Is it possible to use multiple GPUs?
Sorry, currently not.

More GPU cores means for exampe 1080 > 1060, but not 1060 x2 >1060.
That's why 980Ti might perform better than 1070 as the former has more cuda cores.

Lucky_SLS · Mar 16, 2018

Like I said and like listed in the article, the test was performed with a 10 core broadwell cpu. It was cpu bottlenecked in those operations.

More over, u can clearly see that 1070 sli gives 64.1 and single titan xp gives 62.4 (slight difference due to bandwidth maybe?) dual 1080 also tops at 62. Cpu bound?

But 1060 single to sli is from 110 to 82, reason? A titax xp got more cores and bigger bandwidth? Sli 1060 is bottlenecked by its bandwidth? I don't think cpu is the bottleneck here...

Try to answer these questions.

And who told that Cuda cores is not more in dual 1060 than 1060? (these softwares just use the gpu as resources. So sli technically doesn't even come to picture, and 1060 sli is not a thing anymore)

iamacow · Mar 16, 2018

Just so people know Adobe won't use a second video card and all renders are CPU only. The GPU will assist in 3d stuff from After Effects but that's about it for adobe. I have 4x 1080Ti and it makes so difference for 4k editing versus one. So really the second video card is only useful if you are playing games or mining. I'm pretty sure Cinema 4d also only uses 1 card.

Lucky_SLS · Mar 16, 2018

^ that answer is a bit outdated.

Yes some renders use cpu heavily but new renders are coming up and gpu render support is expanding fast.

https://greyscalegorilla.com/2017/08/what-renderer-should-i-use-in-cinema-4d/

But I don't know which renders and work tasks op is interested in or if he is already invested in select renders. So I digress.

n0ns3ns3 · Mar 16, 2018

Lucky_SLS
You presented 0 FACTS that multi GPU will noticeably (more than 0-3%) speed up OPs workflows. Your stubbornness to accept reality is kinda self explanatory - so I'm terribly sorry, but I'm not going to waste more of my time on you as you clearly can't be "saved".
OP already have all the required info so he can made an educated decision.

zionyt27 · Mar 16, 2018

n0ns3ns3 :

I decided to go with a different PC: I still need some help with 2 monitors, a case, and a motherboard. For the RAM I did other to choose the RAM I knew I wanted to use. I need 2 monitors preferably to stay side to side, so a thin bezel. Atleast 120 Hz, I'd rather go with 144Hz - 240Hz, 1920x1080 / 2560x1440. I will be doing photo & video editing (Photoshop, Adobe Premiere Pro, Sony Vegas, Cinema4D), and gaming.

n0ns3ns3 · Mar 16, 2018

Can you post what part you do want to use (CPU, RAM, GPU, PSU etc) ?

zionyt27 · Mar 16, 2018

n0ns3ns3 :

What do you mean by what part I want to use?

n0ns3ns3 · Mar 16, 2018

computer parts.
CPU, RAM, PSU and other that you already decided to buy.

zionyt27 · Mar 16, 2018

n0ns3ns3 :

Ohhhhhh, I accidentally closed the site where I had everything and it didn't save, I have to re-do it then I'll reply with it.

zionyt27 · Mar 16, 2018

n0ns3ns3 :

https://pcpartpicker.com/list/VGhZ8Y . I need 2 monitors with small bezels to stay close together either 1920x1080 or 2560x1440 anywhere from 24" - 29" maybe a little more if needed. If I need a different motherboard just change it to the one I need and same for the case.

n0ns3ns3 · Mar 16, 2018

I have few things to ask you first:
1. why 2x1TB 2.5" SSDs?
2. why Krappen X62 ?
3. you really don't need 1000w PSU - something like RM750x would be more than enough.
4. the sound card is so marginally better than the onboard one and completely useless with the headset as the 7.1 connects with USB.

and another question is about your case preferences.
I really like the Fractal Design for the quality, functionality, performance and simplistic lool
Fractal Design Define C, Meshify C or if you are into a bit bigger - Define R6
Let me know about yours.

BTW, this build looks much more like a gaming one than a workstation oriented with 6 cores/12 threads.

zionyt27 · Mar 16, 2018

n0ns3ns3 :

My bad I meant 500GB SSD, and 2TB hard drive

Whats so bad with the Kraken X62? I watched some videos on people reviewing it and they all said it was a good Liquid CPU Cooler. But if its not good then I'll go with like Cooler Master masterliquid ml240l RGB Liquid CPU Cooler
If 1000w is too much I'll do 850w.
I don't know much about sound cards and how they work so I just chose one with good reviews. I won't be using speakers (at least I don't think so) and don't sound cards make mic's sound better and make headphones sound better?

The case I'll do either Meshify C or Fractal Design Define R6 depends on if they both fit everything...
And I want to do Water-Cooled.

x2 GTX 1080 (Liquid-Cooled) or GTX 1080 Ti (Not Liquid-Cooled)
