I want to create Server based Gaming Rig

Why? For the extreme cost of such a rig, you'll not be able to take advantage of its power with any games on the market. More is not always more.

Please communicate in your thread and not via PM.

Theoretically, the build should work. However, you'll likely need multiple power supplies and an advanced cooling system to manage the heat and power requirements of such a rig. This "industrial" type rig will demand way more than a typical PC.

Practical performance-wise, this is massive overkill for even the most advanced home user.

When you build this, please post pictures. Good luck.

Hi,

The pci-e slots might accomodate 4 Titans. However 2 are 16X's and 2 are 8X's.

And the RAM @ 32GB, 8GB per processor seems lean.

Some examples of 4x Titan:

This one picks a 12 core xeon for 24 threads. The X5690 rates higher with only
6 cores and 12 threads.

https://pcpartpicker.com/b/d2Cypg - is an example.

https://pcpartpicker.com/b/FzccCJ - another one.

Good luck.

Yes, you should be able to 4-way SLI.

Are you actually going to build such a system? Or, is this one of those "dream" configs? Seriously, there is no practical reason to build this sort of system. Zero.

What operating system do you intend to use? 1TB of memory is extreme to say the least and will honestly be a huge waste of money as nothing on the market (or in the next few years) likely to use even a fraction of that memory. I would strongly suggest you not exceed 128GB (64GB or even 32GB would meet your needs).

Just a thought. I really want to see pictures of this mega-system when you are done.

Good luck.

Building this PC is like using a cruise missile on your house to get rid of a spider. 4 titans isn't smart especially with the new HBM cards coming next year. Just wait 6 months to a year and you will have a better PC that doesn't cost as much as a car.

Vineet Ready:

My humble apologies I totally missed the Terrabyte of RAM. It just didn't register.
D'uh. I think I got stuck on the Quad CPU config and 'gaming' in the same build.

Gaming is max'd out at 4 cores, so four fast cores defines the genre with single
core speed still mostly being the standard.

The X5690 @ 8 cores holds no advantage over 4790K @ 4 cores in gaming.

Using the four Titans in a SuperMicro server quad environment doesn't get
the 'ultimate build and forget' designation.

Four Titan X's can't do 3 screen 4K yet for the great immersive experience.

Aside from practical considerations like the amount of time spent setting up
and tuning a four way SLI for what is at best a losing proposition for high
end 4K play at the moment there is a very fast oncoming wave where there
is a stacked memory becoming available which is one of the things needed
combined with the new Pascal chipset design that says it is going to be a
gamechanger, pun intended.

The trouble with trying to tie down the future is that it is so fluid that it can
bulge and leak out in completely unexpected directions.

With all that said, fast cores, dual GPU's and a motherboard that can carry
the load forward for at least a two full generation time frame would be your
best bet. I get the big server base to stand on. But for the overkill to actual
effect ratio this config isn't going to bring enough benefits over time.

The SR2 classified allowed overclocking of Westmere Xeons. By the time you
configured it and found the edges and limitations prices for faster processors
were coming down and more core and faster single core speeds were going
up. If you want to make configuration and tweaking your hobby you can do
things like this.

BUT:

I also think that you should have exactly what you want. That's what I did once but
I had a far lesser budget and a less clear endpoint. For your money you can have ultra
power and the cutting edge that's upgradable. There's no way to use what your plan
called for. And as Knicks said, all your stuff was in the house when you won against
that spider.

It's too early for a terrabyte of RAM. 128GB of DDR4 is sufficient overkill.
On a motherboard that will hold its value and support the full load: SuperMicro X10DAi
throw in a couple of Intel Xeon E5-2697 v3 @ 2.60GHz with turbo mode to 3.6GHz.
There's nowhere to go yet on 4K multiple screens so 2x Titan X is also bang for the buck.
And you should have the best 4K screen like a Acer Predator X34 Curved IPS NVIDIA
G-sync Gaming Monitor 21:9 WQHD Display which you can double up when more
powerful cards become available.
For worry free and long life power you can get a nice new:
Corsair AX1500i ATX 80+ Titanium @1500W or,
EVGA SuperNOVA P2 ATX 80+ Platinum @1600W

Put it in a roomy case:

http://www.caselabs-store.com/bbbb-th10-and-pedestal-by-cpachris/

Again good luck.

Good luck trying to find a case. I am sure the caselabs case ^^ above will NOT work.

Don't be a hater Bossy,

Where there is a will there is a way.

Not being a hater. I am being a person who is confused and dumbfounded as to what case he will use.

Okay, so a server cube like http://hardforum.com/showthread.php?t=1574706 or the other one
I already referenced http://www.caselabs-store.com/bbbb-th10-and-pedestal-by-cpachris/ just
couldn't contain an E-ATX motherboard and custom cooling system? Well, if that's the case, uhm,
another fun pun, intended of course, he could just make like a pasta chef waiting for the spaghetti
to be done and throw it at the wall: http://www.honeytechblog.com/the-ultimate-computer-wall-rig/

Thumbs up on the Picture request. I´d like too see some pictures too when it´s done.

Also 32 x 32 GB rams is just too much - even on the most extreme setup. And I wonder why going for DDR3 rams when the CPU is optimized for DDR4 - just switch mobo to Super X10QBL-4CT - heck. then you can go for 2 TB of rams if you wanted.

4 x Titan Xs will scale horribly

I am am quite interested in a further explanation on why excactly you can get all these parts so cheap with a legit warranty. Your explanation lacks some, to make sense.
