Kill it I suspect.
You may even get away with a single GTX 670 depending on what game you are playing.
This is pretty old, but it will give you a good idea:

"Kill it I suspect" what'd you mean?I'm mainly playing Smite a Moba. I just thought the difference between 1080p and 1440p monitor might be like 720p to 1080p which would be amazing.
670 Sli is a waste of money on a 1080p setup as one of your cards is sat there scratching it's arse.
It doesn't quite work like that in reality, but If you take a card out I suspect that you will see no visible loss in performance at all with a single OC'd 670GTX at 1080p
Your system is crying out for a bigger monitor to fully untilse your graphics cards.
You could go bigger than 2560 x 1440 if you chose too.
Are you yanking my chain? Surely you know all this?
"Are you yanking my chain?" The simple answer is no, you haven't exactly answered my question I wouldn't buy a second 670 for a 1080p monitor what I was asking is if I was to purchase a 1440p monitor would another 670 be beneficial for the game I play which is Smite.
You'd be better off asking on a community forum which play that game as I've not seen anybody on here with that set-up who has mentioned playing that game.
Not saying there isn't - you may just have more luck.
Things to establish is what kind of CPU usage does the game do? 1,2,3 or 4 cores?
If it's only 1 or 2 it's probably going to be CPU bottlenecked and as such SLI would make no difference.
A good way to test would be to buy a 1440p monitor if this is what you want to do and test performance with one card and record GPU usage. If it's less than 95% consistently then there's some kind of bottleneck in play - be it CPU or game engine - and a second card would be wasted.
I run a 1440p monitor @ 120hz on a single 670 and its fine for most games, however I do struggle to hit over 120fps in some titles such as BF3 with all settings maxed out.
Everything runs at a min of 75fps which is my minimum when playing games.
I've also thought about going to SLI but don't think that cost will be worth it

Ok I this is the way I see it:
First step is to see what frame rates you are getting with a single GTX 670 at your current resolution 1080p I take it?
Do you have a single GTX 670 at the moment or do you have two?
The next thing to do is see if the games you wish to play have an SLi profile, if they don't it will be pointless adding a 2nd card.
1920 x 1080 = 2073600 pixels
2560 x 1440 = 3686400 pixels
Therefore 2560 x 1440 is approximately 78% larger than 1080p
From this you can decide if it will be worth it.
If you are getting 60 fps at 1080p you should see 34 fps at 1440p
60 / 1.77 = 34 (ish)
This is approximate but it will give you a good idea. I have no personal experience of the games you are playing, but the GTX 670 scales well at 1440p, the GTX 660 Ti does not due to memory bandwith.
Well BF3 is the one of the main games that does stuggle for me, but then I don't play it on ultra for this reason. Turning off AO and AA tends to do enough for me to still have it looking good and running at 75fps+
You shouldn't even worry about WarZ for now, its in Alpha and hasn't been optimised. I also play this and the engine does not go above 60.1FPS no matter what settings and running in LOW on 800x600 gives me the same FPS drops at LOW on 2560x1440 (both using 32% GPU and 30% CPU).
Even when running on ULTRA my GPU usage never goes past 75% although when I upgraded to Windows 8 I so much less FPS drops than before, but they still occur.
But either way, don't judge performance of your system on a game that is in its Alpha.

BF3 is CPU limited, you need to get an i7 to see higher framerates, even with GTX 670 SLi
Only with SLI - he has a single card.

Hard to say really. Rusty will tell you who it was, but a guy was getting 50 fps lows in BF3 with an i5, he switched to i7 and his lows were 80 fps.
This was with GTX 670 SLI.
If you are seeing 50 fps lows with a single HD 7970 it is more than likely your CPU not your GPU.
i5 and a single card is still a good balance even in BF3 however.
Bit too vague with the CPU types really, could have been a first gen i5 and second gen i7 which would see huge performance boosts.

I was Ivy @ 4.6 with full custom cooling loop, it surprised me.
DaveBeast said something similar actually. He was going to make a video to prove it, however he didn't so until i see that video i remain doubtful.
There is a spot on metro where me and other i5 users reported fps dipping a bit, he said it didnt happen to him and his i7. However since the wonder 12.11 drivers that dip no longer happens.
For that reason i remain doubtful.

This was with nVidia cards so the ATi 'super drivers' were not considered.
