I'm looking to create a build that supports 3x Dell U2713HM (2560 x 1440). I already have these in my current build (I run three different PC/macs off them now for work and play), but I want a graphics card and build that will support running all of these smoothly from one machine. For this build, I'd like to focus on just getting ultra gaming performance on 1 monitor, with twitch streams and other multi-tasking running on the other two monitors. Here is what I have so far, but certainly recommendations are welcome:

Intel Core i7-4770K Quad-Core Desktop Processor 3.5 GHZ 8 MB Cache BX80646I74770K
Asus Z87-PLUS DDR3 1600 LGA 1150 Motherboard
Noctua 6 Dual Heatpipe with 140mm/120mm Dual SSO Bearing Fans CPU Cooler
G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM 1600 (PC3 12800)
Samsung 840 Pro Series 512gb Solid State Drive MZ-7PD512BW
Western Digital Bare Drives 3TB WD Black SATA III 7200
Corsair Professional Series HX 750 Watt ATX/EPS Modular 80 PLUS Gold (HX750)

What graphics card should I go for? Given the ultra hi-rez monitors, do I need SLI/Crossfire?

I don't want to go overboard on this build, so while I realize that means something different to everyone, I'd like this to be a high end build but maximizing everything for that last 5-10% isn't really necessary because I usually build a new machine every 2-3 years anyway.

FYI: I don't need to game at 7680 x 1440 although extra points to anyone who can recommend a 2nd solution that would make it feasible (at an obviously extra cost!)

1. Yes 3gb vram is sufficient for 1440p gaming.
2. I'm pretty sure the crossfire options would be better than a single GTX 780 ti, but a single GTX 780 ti allows for future SLI while going crossfire 280X/290X is the furthest you can go. Generally, it's better to just go with the single strongest card because it allows for better upgrade-ability.
3. Hmm maybe not. Not many people actually game at 3x 1440p, so I'm not too sure. I'll assume you might want 4gb of vram, so perhaps a R9-290 may be a better option. However, if you do plan on going for the R9-290, wait for the aftermarket coolers on them. The reference cooler runs too hot and too loud for you to even consider it.

You can probably go with a cheaper motherboard. The ASRock Z87 Extreme4, Gigabyte GA-Z87X-D3H, or Asus Z87-A are all viable options.
Stick with 2x4gb of ram. 16gb of ram is overkill for games, 8gb is the standard size for a gaming rig.
Drop the SSD to a Samsung 840 EVO. The Pro is much more expensive and doesn't really offer anything much over the EVO. Also, you'll be fine with 250gb if you use it wisely. That would save a lot of money there.
For the HDD, the Seagate Barracuda 3tb would be a much cheaper option and not that much slower either.
You may want to upgrade the gpu to a quality 850w psu from XFX, Antec, Corsair, or Seasonic if you ever want to SLI/crossfire.
Since you're only gaming on a single 1440p monitor, you should be fine with a GTX 780. If you want, you can go for the GTX 780 ti for the extra performance.
If you want to game on all three 1440p monitors, you'll probably want to go with SLI GTX 780 or 780 ti.

Thanks!

Couple questions:

1) Will the 3GB of RAM in the 780 Ti be sufficient for max rez games at 1440p on one monitor? The card looks like a beast I just understand that 1440p (even on one monitor) pushes a lot of cards to their max

2) Is the 780 Ti going to be better than say two 280X's or two 290X's in Crossfire? I've read having SLI/Crossfire setups can sometimes be problematic, but if that setup is better than one 780 Ti, I might consider it.

2) Do you think the 780 Ti's only 3GB of RAM will be sufficient for gaming on all 3 monitors at once, even in SLI?

Really appreciate all your help!
