mb : Maximus VIII hero
cpu : intel i7 6700k
vga : Asus gtx 980 ti SLI strix
HDD : WD Black 4TB 64MB Buffer HDD
ram : Trident Z 16GB 8GBx2 3200Mhz CL16 DDR4
case : CM Storm Stryker
SSD : Samsung 950 512gb
power : Corsair HX1000i 80Plus Platinum Power
cpu cooler : Cooler Master Nepton 240M Liquid CPU Cooler




will they work well together ?
each VGA will get x8 PCI lane and x4 for PCIe ssd right ? ( since z170 chipset has like x20 pci lanes i think right ?)
will i have the full speed of Samsung 950

enough power ? ( i will buy a high end Amp/Dac soon that connects on USB called mojo , will that use power or something ? anything to worry about ? )

While you most likely don't need 1000 watts for SLI and overclocking, you'd definitely want a good 800 watt PSU as a minimum. The power draw of a 980 ti can easily hit 300 watts (depending on temperature and GPU version).

You are also correct. The Z170 has 20 PCIe lanes meaning you can use an M.2 SSD and have 8 lanes for each GPU.

Edit: I personally don't believe you need to change anything.

I would argue that you have too much wattage, you could get away with as little as 750w. Another thing you might want to consider is saving a bit of money on that motherboard- You can get the same performance for about half of the price, only the aesthetics justify the markup. All of that looks good, you could consider an h440 instead of that case you have, in my opinion it looks better and has a nicer layout, with really nice cable management options, but it depends on what you like. have a good one :)

I'm going to have to disagree. Yes, if you have an OC 980Ti 300W. If he OC his 6700K, let's just fantastize and say he has a nice OC and 150W. Rest of system - let's overexaggerate and say 125W. 575W it adds up to. And that would be under the worst of the worst torment. Normal gaming, normal load, I would say more like 400W. So you're right about 800W being the sweet spot for efficiency, but I disagree about it being the "minimum".

so if i use this case , considering i use all the 16 PCI LANES of my cpu and connect them to my GPU's , each x8
will i have the max performance of my PCIe SSD samsung 950 , considering i'm using z170 pci lanes , is there any difference if i use CPU pci lanes than using my motherboard's PCI lanes ? will i have less speed ? or this RIG is just fine ? should i go with 5920k and x99 considering 5920k has 28 PCI lane ?

There's no reason move to the X99 chipset for gaming. Increasing lanes will not improve performance of those GPUs.

but is there any difference in speed between using cpu PCI LANES and Motherboards PCI LANES ? considering samsung 950 512gb will have a 2200 read speed or something , is there any difference between z170 PCI lanes and cpu PCI LANES ?

I don't see why there would be. I haven't found anything that says there is. You could also message the Moderator in the thread I posted and see what he says.

chipset pci lanes have latency problems and will not give you the same performance as cpu pci lanes, as they have to go through the chipset as well as the cpu. They are inferior, if you can always use cpu pci lanes

I'm going to have to ask for your source on this one. I've spent about an hour looking for information about the additional 4 lanes from DMI and also performance differences on the PLX lanes of the Z97 chipset. The only thing I was able to find was an article with Z77 Ivy Bridges using PLX chips for lane expansion. The article did state there would be latency but no results were provided just on if the latency hurt performance.

@omidelf,
From what I've found you shouldn't have any performance issues. Those additional 4 PCIe lanes utilize two SATA ports.

Ah yes, the youtube videos. I personally despise youtube videos. It's not because I think the people who post them aren't experts, it's because there's always information missing. Paul is a good guy but there's no numbers there so at the end of the day you have someone just talking into a camera.

Also, it sounds like all you heard was the few words "latency" and "PCIe x4 slot" in the same sentence. Paul stated there would only be latency issues when all of the SATA ports were utilized. https://youtu.be/_7zW4pqLDIc?t=5m44s
