Dual 760's or Single 770?
Paired with a 4670k which would be the better option? A single 760 seems to give good performance at 1080p so it wouldn't matter so much if SLI didn't function in certain games.

Not sure what you mean by "similar performer". In order to get a single GPU that posts the same framerate as a pair of 760's ($500), you need a 780 ($650), and you'll need to overclock the 780 on top of that. A pair of cards is massively powerful for the price.
The benefits of using a single GPU are universal support, and no frame latency (and of course, the option of buying a second card later). However, Nvidia's frame metering is very good (almost no frame latency for SLI), and nearly all games that would need the extra horsepower support SLI and crossfire.
There's almost no downside to using a pair of Nvidia cards. AMD's crossfire still has some frame latency issues to work out, but the 13.5 beta 2 drivers are a big step forward.
SLI 760s are better than a single 770 by about 7%. You really wouldn't see much of a difference at all. Running a single card is always better than running two. Especially when you don't have a 700/800 watt PSU. If you already have a 700/800 watt PSU, go ahead and run SLI 760s. Whichever one you go with, it will be around same performance

I am assuming from the original post that you are gaming at 1080p. If that's the case TechPowerUp offers some insight into how much more performance the GTX 770 gets over the 760 at 1080p gaming.
The stock GTX 770 has a 21% performance boost over the stock GTX 760 according to these charts.
The EVGA GTX 760 comes up only 13% under the stock 770 in these charts.
Taking into account that you can overclock the aftermarket GTX 760's you can almost close that gap to get 770 performance out of a 760 or at least come close to a non-noticeable difference. Some level of AA may still be unattainable on the 760 but for 1 monitor 1080p gaming the GTX 760 offers greater value while the 770 offers better performance.
In the end the most given solution is to get the best single card one can afford then go SLI in the future if performance levels are not reached (or if there's a good clearance sale ) if your case/PSU can handle it.
