What kind of FPS boost will the 8gb models of GTX 970 give for 1440p?

Especially considering i'll already have 8 gb since i plan to run the 970 in 2 way SLI. Is it really worth the 8gb model or are we talking no difference / 1-2 frames per second difference

You will see no benefit at all unless the game requires more than 4GB at your settings.
At 1440p, no game will reach this with any available in game settings.
You could maybe get there in Skyrim with mods, but it would be very easy to keep it under 4GB.
These cards are aimed at Crossfire setups running 4K monitors or multi-monitor setups.
The 4GB version will be fine.

SLI is not used for AMD cards, this is an Nvidia technology.
Both crossfire and SLI use each cards memory locally for that card, this is not shared.
That means if you have two cards each with 4 GB of VRAM you have an effective 4GB of VRAM.
Two cards each with 8 GB of VRAM give an effective 8 GB of VRAM.

Roughly speaking, GPU power and VRAM requirements double every 2.5 to 3 years from what I have observed.
This suggests that in a year from now you might need more than 4GB of VRAM to run 1440p at the highest detail settings, but that current cards probably won't have the processing power to run these settings anyway.
I think a GTX 970 with 4 GB of memory is ideal at the moment, and will still be fine for years to come if you are prepared to lower the detail settings to be more like current games.
If you always want to play with the highest settings, buying an 8 GB card now won't necessarily help with that. You would still need to upgrade to the next generation of cards.

That I have no problems with, as long as the dip in detail isn't that much (sometimes it isn't really noticeable, so I have absolutely keeping details down to keep the game playable).

But I have a certain itch to SLI 2 970's to go with my Asus Swift, the problem is that I bit the hook and already bought one 970 4gb to put into my old rig while I waited to finalise my new build, something I have second thoughts about now..

I am reluctant to let the 970 go (IE return or sell it) because I got no coil whine from that particular card, so I am rather happy with that purchase. I was dead set on getting a second 970 to SLI, then i am starting to get torn lol (wait for a newer gen card with higher VRAM, or just get the SLI the 4GB now and turn the details down when needed). Chances are I will turn down details some to get most out of my monitor so I am leaning quite heavily to getting a second 4GB 970.

i highly reccomend a 970 SLI at least for the Asus Swift (if thats the 1440p 144hz monitor i think it is). Otherwise you're just not hitting anywhere near as high frame rates you can get on that beast of a monitor. In fact in some titles (crysis 3) it takes 4 GTX 980s to hit the 144fps limit of that monitor on highest settings.

a single 980 can't compare to two 970s at 1440p at all and they are roughly ismiliar in price, so you're really better off getting that second 970
