No, it's not worth the upgrade.
You can get two 760s for $250 less and still get more performance than any 780 or the Titan. In two years' time that $250 will buy you a new single card that will outdo anything out now, including, again, a Titan.
Although the 760 SLI will be able to max out any game out there for far longer than two years, which means you can put off another upgrade by 3-4 years, by which time that $250 buys you a card better than two Titans in SLI.
The only thing that might limit the performance of dual 760s with future games is the 2GB of VRAM. But if you don't game on 4K resolution of multiple monitors, that's not likely going to be an issue. Even then, you can prevent that from ever becoming an issue by buying two 4GB 760s. That's more memory than a 780, lots more performance, and it still doesn't cost you more than a single 780.
The only scenario where the 780 is worth it is if you either don't have an SLI motherboard or you plan to SLI the 780 at a later date. In any other case the 780 simply is not worth it, neither by price-performance or absolute performance.
In a couple years, upcoming games like for example, if there ever is, a Crysis 4, two 760s will struggle, and low fps = stutter. Plus, 2 cards need a 750 to 800 watt PSU. And an SLI capable mobo, and SLI capable PSU. That said, 780 is a better bet as he can always find the money to upgrade to 2 or get a better PSU or whatever else the OP wants later on.
Sorry but that's just awfully incorrect.
Why do you think two 760s would "struggle" in two years? That is highly unlikely given that they're much, much faster than a GTX Titan now. Do you expect Titan, a $1000 card, to struggle with games two years from now? If the 760s will struggle, then so will the 780 and the Titan - and much earlier, too.
And pray tell, how would buying a 780 make an upgrade more affordable? If you buy two 2GB 760s you'll save $160 compared to a 780. More if you buy the second 760 three or four months from now and not right away.
Two years from now you can get a card that is faster a Titan for $250, or in three years a card that is faster than two Titans in SLI. The $160 you saved now is going to go a long way towards that upgrade.
Not that you need to upgrade in 2 years if you have SLI 760s. They will easily last you for three years if you don't insist on absolute highest details in
every game (they will do them in most, even two years from now). Meanwhile, buying a slower 780 means you'll have to sacrifice details that much sooner
and you'll have less money to make the upgrade to begin with.
Lastly, you really don't need an 800W PSU for SLI. You can run dual 760s on almost any system with a 650W PSU. A 750W PSU will easily handle two 780s with power left to spare.
