Will my system not bottleneck the GTX 1080, or should I switch to Z170 or X99? Achtung! Long!

Thanks for reading and for all responses. OK now lets get down to the nuts and bolts of the situation. Currently I have a;

MSI Z77A-GD55 motherboard,
Intel i7-3770k CPU @ 4.2 h2o cooled,
16Gb of G.Skill RAM @ 1600 (4X4GB) with XMP profile,
Corsair TX750 watt PSU,
Sandisk SSD 120Gb for OS,
Samsung 840 EVO 250Gb for my video games,
four WD Blue HDD's run in RAID 1+0 for files, data, etc.
I currently am running two MSI Gaming GTX 780 GPU's in SLI,
my monitor is a 25.5" Samsung SyncMaster capable of 59/60hz. It also has a coaxial cable in the back and got it before I was using it as a gaming monitor just as a HDTV (1200p, 1920x1200.)

I guess people would call me a NVIDIA and Intel "Fanboy" because I would never run an AMD CPU ever and I prefer NVIDIA GPU's but have used AMD GPU's [(for alt-coin mining machine) 2x7850's]

So what I am asking here is with my setup and mind you all my hard drives including SSD's run over the SATA ports. The two SSD's on the SATA III 6Gb/s and the four WD Blue's on the SATA II 3Gb/s.

Will I be able to run a NVIDIA GTX 1080 without a CPU, RAM, Chipset bottleneck? I will wait until the non-stock GPU's come out as I prefer MSI and would like to either buy their Gaming line GTX 1080 which comes presumably with an overclock and custom cooling or depending on information here on Toms and elsewhere wait for a Pascal 1080ti or even a Pascal Titan. I wished it had the newer memory (not GDDR5X, HBM) but whatever. If it doesn't make the GPU's run that much slower I don't really care. Also I will be upgrading my monitor. I want an IPS, around 26" and am looking for one that has G-Sync built in and would really like the Asus X34 Predator which is the 21:9 with G-Sync but would also consider a 4K with G-Sync if prices are substantially lower than the ultra-wide but I really do want the ultra-wide badly (just not for over grand).

I apologize for the length of this forum post. I just sold my two GTX 970's on Amazon to prepare buying an MSI GTX 1080 when it is released. Now the question is will my system, as built, be able to not bottleneck the 1080 or do we need to wait for benchmarks and real-world experience for an answer?

So that's the question. Another is I kind of want to go with Intel's new i7-5820K or i7-5930K. The reason for this Is I would like some USB 3.1 A and C types and I would have either 28 or 40 PCIe lanes which would allow me to run the 1080 with a m.2 using 4 PCIe lanes. I know I would need to buy new memory but I am trying to offset all costs by selling my current rig if I hear that it won't be able to max the GTX 1080. Honestly I really do want to jump over to the X99 and have the extra PCIe lanes to run my OS on a SSD using those. In your opinion with this GPU in mind would I be better off with a 6 core, 12 thread i7-5930k, i75820k or i7-6700k and go to that chipset?

I feel like gaming will probably be better on the i7-6700k but the 6-core allure is kind of right in my face especially if they are both going to use DDR4 RAM. I am truly lost and maybe I should just wait for benchmarks but I'm just not sure if the 6-core 3.3ghz 5820k or 3.5ghz 5930k will perform as well as the 4 core 4.0ghz 6700k in gaming and of course I want to future proof as much as possible if I do have to switch off my good ol' 3770k which I water-cooled and have running at 4.2ghz 24/7 without a problem. Might try bumping it up to 4.5 if the GTX 1080 is a good fit.

Thank you for reading my post, and I sincerely apologize for the length of it. I just have so many questions on my mind and can't decide to stick with my rig and just get the new GPU or if I should do a total upgrade to X99 or Z170 and a 6-core processor or if a Hyper-Threaded Quad-core at a high clock would be better. Ohh the life of a PC gamer. Masochists all of us.

Normally I would recommend to wait on upgrading your system for Intel's next chipset, but it's very vague as to its launch, and isn't slated to be in volume production until late this year. Your choice on the wait. As for the choice between sockets, my stance is this: use the Z170 for 1 card. That's all it has lanes for. For SLI, my opinion is not with the consensus - I recommend going Xeon for SLI. For a while, it wasn't as cut and dry, I had recommended the 2011 sockets, but the 5820k only has 28 lanes, whereas the 5930k has 40. Xeon is able to provide more lanes and 2 cpus for the same price. The reason this is in the dissent is because people honestly believe that Xeon is inferior in gaming, due to lack of proper coding in games.
