I have been running EVGA 960 SSC x 2 and using EVGA SLI Bridge.  Working great, until I upgraded to 3 monitors, 27", 1080p, now I'm getting way to low FPS.
My question is, I would love to upgrade to EVGA GTX 1070 series, but i'm lost with all the different choices.  
I was looking at the FTW, but different reviews I'm seeing.  Still lost.
Does anyone have in site on one to buy.  One that just works great with the 3 monitors.
I'm running 5760 x 1080 resolution.
Thanks for any help that comes my way.

I think you should be good with a single 1070.  If you're planning on 2x 1070, then you might as well get a single 1080ti and you'll be golden.

As for the different models, they vary with (1) factor clock speed,  (2) led/non-led/multi-color led, and (3) acx 3.0 vs icx cooler.  i dont have a breakdown but you should look at whether you want Single LED/Multi-color LED/no LED lights as a starting point, then once you decide that, decide the factory clock speed you want and that should get you down to maybe 2 cards that differ in color.

personally I recommend the 1070 FTW2
