SLI 560ti's keep them or?

I have been thinking about getting rid of my 560ti's, which have been great by the way, and going to a single card solution like a 770. I don't game near as much as I used to, and I think a single card would be a better fit as an occasional gamer (COD, Skyrim) Anyone have input why I should or should not make the change? Its not that the 560's in SLI are not providing enough performance for me, I just would like to move to a single card. Would appreciate your thoughts, of course I am not made of money, but cash is not a huge concern.
 
If you want to switch to a single card do it. Less heat/noise, and just easier overall. if you are fine with your setup and dont really have/want to spend the money then your gpus will be fine. The 770 is a great card, and should easily max cod (i dont have much experience with skyrim so i cant say)
