As for Civ 5 and triple-wide support, I don't have much to add. You may want to consider a complete uninstall/reinstall of Civ 5 or, as you've suggested, try rolling back to an older NVidia driver. It could even be an issue with scaling to 3 cards in SLI. Try disabling one or two of the extra cards and see if it makes a difference.
I personally ended up making a concession for Civ 5 and just playing 1920x1080 because the UI was so unfriendly at 5760x1080 and I couldn't get over the weird aliasing on territory borders in triple-wide. Did anybody ever release any decent UI modifications for it? I'd be happy if the important UI elements were centered or either all on the left or all on the right, but having them split between the left and right was just too much horizontal scrolling for my tastes.
