Probably the reason I won't go with a Titan is using some money on a new desk or joystick then anything else.
For the motherboard at the end of the day, I am probably not going to do some overclocking as much as I have a bit of an interest in it. The X99 Strix mobo as lehtv mentioned earlier fit a bit with doing some lighting which is more then likely the extent of anything I will do. I guess OC'ing the RAM is something I might consider as well but the board looks like it supports that if I ever wanted to go that route.
The Canadian price for the GTX1080 is horrific. $900 is dang near Titan X price anyway ($1,200). Problem is I can't find any of the new Titan X (Pascal) in Canada, just the old one.
Seems like it's only available direct from Nvidia (but currently sold out)

I totally agree with Aigomorla though, 1x Pascal Titan X around $1,200 would be way better than 2x 1080 at $1,800.
Let's put it into simpler numbers, let's say 1x 1080 is performance 1.0, that makes a 1070 0.8, and a Titan X 1.3
When SLI works lets say it averages 70% scaling. Also consider it's likely to only work in maybe 20% of games. And the other downsides of 2 cards, more power/heat & usually less ram/bandwidth.
If we look at the 1070, 2x it would be performance 1.36. At a cost of $550 CAD each, 2x 1070 looks like a poor option next to a $1200 Titan X. And Nvidia doesn't support 3x SLI anymore.
2x 1080 then would be 1.7, impressive, but only in that 20% of games. Compared to the Titan X 1.3, it's 30% faster 20% of the time and the other 80% it would be 30% slower (back to 1.0).
Consider cost, a Titan X is 34% more expensive than the 1080 at $900, but offers 30% more performance. 2x 1080 would cost 50% more than the Titan X for that occasional 30% gain, but more frequent loss.
And again, don't forget that 2x 1080 uses more power, creates more heat, has less VRAM (the 2 cards don't add up their memory), and less bandwidth than the Titan X.
At least in Canadian prices, the Pascal Titan X actually looks like a pretty good bargain, if you buy 1. And it's performance is enough even in 4k to last until it's replacement comes along in a year or so.
I'd like to suggest this to you as well:
https://siliconlottery.com/products/6800k44g
These guys do ship to Canada, and they guarantee this CPU to run at 4.3GHz+ at 1.38v or less (with a good MOBO/cooling). They offer even faster options, but this is a good balance of speed, voltage, and price. Since spending more only gets you extra cores, this is an easy way to buy more performance (without taking the risk yourself). At this speed it will keep up with a 6700k in single threaded stuff, and beat it down with 50% more cores in everything else. I would only suggest the 6800k for single GPU setups though...if you really intend on going with an SLI setup (at any point) then I'd highly suggest getting the 6850k:
https://siliconlottery.com/products/6850k44g
This is because the 6850 offers more PCIe lanes (40 vs 28), which you'll need if you want to feed 2 high end GPUS (2x16=32 lanes) and PCIe storage (typically x4 each) and any other peripherals like Thunderbolt/USB 3.1. If you plan to keep the system for another 5 years, the price difference between these 2 CPUs is minimal.
Here's a possible build I tossed together:
http://ca.pcpartpicker.com/list/q2zk9W
It includes an overpriced 6850k (the 40 lane option) as if you were to buy the OC version from siliconlottery.
32 GB RAM (why on earth did you pick 16GB?!) This is a nice moderate speed DDR4-3000, at a good low latency 15-15-15-35 and with a fairly low profile heatsink
Asus X99 AII much cheaper and nearly identical to the ROG Gamer, it drops the wifi and some software (ROG cache, internet optimizer, and audio overlay)
NH-D15, vs NH-D15
S Difference is the S version only has 1 fan (vs 2). For 10$ extra the second Noctua fan is totally worth it even if you use it elsewhere (those fans are like $30 each)
2TB 850 Pro SATA only but still crazy fast and you get double the storage for your money. Has a 10 year warranty and insane 300TB endurance (install/uninstall as many things as you want)
Corsair 760T Just an alternative case for you to look at. Similar price range and high end features, and a clear side for all those LEDs you wanted. Clearance for thick radiators top and front.
750 watt EVGA P2 these are fine units, this is the smallest in the P2 line and $70 cheaper. 6800/6850 OC @ 1.38v max is 200 watts, Titan X OC is like 300 watts max. Lots of room to spare.
If you want to go 1080 SLI, then the 850 watt unit would be plenty, it's $40 less than the 1,000w. If you want to run
ANY 2x GPU (like 2x Titan or some future power hog) then go for a 1kw unit.
