AFAIK that LG monitor is pretty new, so that could be the reason.

I would only get the UltraGear.
It is relatively new and the price has just come down. When I was looking at it the sale price was $1200.
 
The Dell is old tech and overclocked. 
 
I was going to get the Ultragear to replace my old Samsung 3440 X 1440 60hz monitor but in the end I went for a LG 3840 X 1600 ultra wide instead. 
I will go Ultragear when the 3840 X 1600 version comes out.

I have the Cosair H115i Pro running stock fans and have no problems.

You can be 'mature' if you'd like but the issue still remains that you weren't providing correct information.  The Maximus line has more fan headers, period.  To say it doesn't only confuses OP.  If you would have taken the time to read through the material that ASUS provides on their website you'd see your mistake.  Don't just jump to conclusions because you think you're right.  Confirm your assumptions with actual evidence.
 
And I'll be just fine sweetheart don't worry about me.

good comeback kid, keep it up and you be on here for a long time. 
 
i will be the mature guy and just ignore you
have a nice day

You're not sure...
 
That's the only correct thing you've said in this thread.

why not add aio/pump headers in? you can run fans on them perfectly fine.
i quoted the strix board not the Maximus so not sure why you're asking about it.

No idea how this spec site counts headers, but you're right
 
Was too lazy to look at mobo layout, was lazy, got punished.:) 

Netherland boys unite!
 
Lets count pumps too then.  We'll add everything in since you seem to have failed to add the extra Maximus PWM headers.
 

 
again I'll let you add them up

i count at least 6. but could be my bad eyes tho
maybe actually look before you make a smart comment <3
 

What Velcade has written is on point. They all pretty much perform the same if you're just gaming. If it were me, I'd probably go with the Hero since it has a code display which is extremely helpful for troubleshooting.

I'll let you count them.  <3

Think they offer the same amount of fan headers. Rest of the information is great <3
Z370-E :
Case fan headers 3x 4-pins
CPU fan headers 2x 4-pins
 
Maximus X:
Case fan headers 3x 4-pins
CPU fan headers 2x 4-pins

Both are great boards there are a number of differences but in regards to performance (FPS or applications or general overclocking ability) they will essentially be the same.
 
In this respect, the biggest difference is the VRM design and components they are higher performing with better efficiency and lower operating temperatures. Think about it like buying a cooler. You can get a Noctua U12S or Noctua U14S both are great and both allow for generally the same OC range but the 14S will offer lower temps. In most situations, this does not make a bigger difference but some users prefer to have something running at a lower temp.
 
Then again if you really were looking for pure price to performance you could drop down even further to the Z370-A and still have an outstanding OC with great quality and features and functions.
 
Keeping the direct comparison in play some other key differences that increase the cost and are dependent on your want and needs for your build.
 
The Maximus line has a more advanced (higher end audio design) which features a specially binned version audio codec while also having a DAC chip onboard with a few other improvements. If you have a decent pair of headphones you will be able to hear the difference. If you love audio it is a nice upgrade.
 
For serious memory OCers the topology on the board is optimized for higher frequencies. if you are not considering 3800+ DIMMs do not worry about this.
 
The Maximus line has additional onboard headers and buttons generally for bench testing setups and enthusiasts (start button, retry button, debug led etc).
 
The Maximus line offers more back IO (USB ports)
 
The Maximus line offers more fan headers.
 
The Maximus line offers on board CLR CMOS button - some OCers really like this but if you use our Auto Tuning technology feature which is on both boards you will generally not use this button. It is more so suited for manual OCers
 
The Maximus line offers USB BIOS FLASHBACK - This is a nice option in the event you need to update or recover your UEFI ( BIOS ) on a low level. even if the system does not post or you do not have a CPU, Memory or Graphics Card installed. You just need a working PSU and connected and you can directly update the UEFI.
 
 
 

Overclocking via MSI afterburner with no Voltage mods should not affect the lifespan of the silicon (the VRMs may be a different matter),  messing with voltage on Pascal does drop lifespan though... 

If you're planning on overclocking then an 850W unit would be fine. An RMx or RMi would be fine.

...you drastically reduce the expected life of the cards drastically while also the power consumption goes through the roof.
Its entirely possible to push some GPUs so hard that they consume double of their original power while only getting 10% higher clocks...
 
Sorry to say but it doesn't make much sense these days no more.
In the olden days, where +50% was easily archieved, sometiems even more than that, it was quite a good deal. But Graphics card never overclocked well and were always used at the upper limit...
 
As for CPUs:
In the Time where the whole series was just the same clock speed, you could have gotten the slowest one and overclocked it to be as fast as the fastest official sold one...
But those days are gone now and the CPUs aren't differentiated by the Clock speed much these days (well, at least for AMD)...

Stock 1080tis are rated for 250W but with overclocks (even factory overclocks) and GPU boost they can go higher than this and can hit 300W under peak load. For example your Asus Strix is rated for 275W TDP with its factory overclock and EVGAs FTW 1080ti is listed as 280W with factory overclock. So allow 600W for the GPUs. Your CPU will be 95W stock, but overclocked will be a bit higher. Assume around 5W under load for each of the 3 drives. You could be looking at up to 700-750W under peak load on the system depending on overclocks.
Throw in all the RGB fans and controllers, RGB keyboards, CPU cooler, etc and the estimate PCPartPicker gave of 770W peak isn't too far off.

As previously mentioned, you could most probably get away with a 750W PSU and never have any issue with it, but personally I'd look for a really good quality 800W or 850W unit just to give you that overhead in case you want to do some heavy overclocking on CPU and GPU. Also gives a bit of buffer if you add in new parts or swap the 1080tis for 11xx series cards later on.
 
Agreed, I definitely wouldn't power 1080tis in SLI with a 100W power supply

As Herman suggests, you don't need a 1000W PSU for the system outlined in the original post.
The CPU won't draw more than 100W
The GPUs won't draw more than 250W each
The other components' power consumption is marginal, and if you add it all together you end up with a system not needing more than a 600-700W PSU.
Overclocked and at really high loads, you might need even more wattage, but it depends on your use cases.

a good 750w unit will take two 1080tis just fine, no need for a 1000w psu.

Not yet, been trying to find a used set to pick up. Then I have a guy who said he'd loan me his 1060Cs so I can review both at once. 

Yeah, the M1060 looks to be a mixed bag actually, I've seen some praise it like it was the second coming, others say it suck with a couple pointing to Monoprice's lack of experience when it comes to damping and QC factor being major cons. Have you had the chance to actually try the M1060 yourself? It really depends if the sound signature of the M1060 suits you......but it may not.

Monoprice DAC amp is a good tpa6120a2 based amp, reasonably cheap.
you didn't really give a budget.

monoprice usb dac looks better the the headphone amplifier or you could go with the dragonfly red.
 
If you really want to push those to the fullest you could get an audio gd nfb 28 or one of the other audio gd headphone amps.

If you want strong and durable, have a look at Ergotron. Though the quality does come at a price.
