Yes you can run 2x gpu's independently with no problems, but why are you wanting to run like this, what are you hoping to gain. Having things running on your other screens while gaming really doesnt take much power from the video card at all (I run 4 monitors from my amd 7950). If you are wanting more power for gaming (yes gaming at 1440p will take more power) you would get more of a gain leaving your monitors plugged in the way they are and adding a second 670 in SLI. This will double your video power and still allow you to run your monitors the same, vs simply moving your other monitors to another card but still having the same amount of video power in the end.
I get what you mean about just adding another card for SLI. Problem is, at the time I purchased my 670 FTW, I acquired it at a certain price. When I build a new comp down the road, I will have a hard time finding the 670 FTW at a reasonable price due to low supply. It would make more sense to just buy a 7XX card or 8XX card by then.
I was under the impression pushing 1440p, 1600p, or higher would require a lot more graphics processing power, since the cards are not capable of pushing that many high resolution monitors off a single card? I understand 1080p is doable as I'm doing it now.
