I'm not gonna waste anymore of my time on tommybhoy, as he clearly lacks reading comprehension skill.

I'm not the only one who thinks the GTX460 768MB would be more than enough for your current res, and you don't really 'need' a faster card until you up your res. GTX460 768MB would have no problem maxing out majority of the games at your current res, and you would hardly notice the extra speed of GTX560/6950 over the GTX460 768MB until you get a higher res monitor, or unless Crysis and Metro2033 is all you play.
Are you refering to your GTX460 768 at 1680 res, or GTX570/6950 2GB at 1920 res?
I already answered if it's regarding the GTX460 768MB, as for 1920 res, even overclocked GTX460 1GB/6850 would max out almost all current titles, bar Crysis and Metro2033.
As for how demanding upcoming titles are, nobody would be able to give you a reliable confirmation until some benchmark or demo is available. Until then, it is all just guessing game and one person's guess is not more reliable than the other. Rather than playing the guessing game and upgrade the graphic card now, why not upgrade when your current card is really not up to it in the games you play? It only takes average 1-2 days for the card to reach your door after you place the order
If you are rich and blowing money don't matter to you, then sure you can just upgrade everytime a faster next gen card is out. But if your funding is limited, upgrading graphic now would mean you would most likely won't have enough money by the end of the year for upgrading to the next gen card.
For all we know the 28nm process next gen card could be much faster than the current range cards (it's not unlikely considering this gen card is just a stop-gap generation with the 32nm process got skipped, and the cards are not really hugely faster than the previous gen i.e. 6950 is only around as fast as 5870, 6970 is only around as fast as GTX480, GTX580 on the same clock as GTX480 is only around 6% faster, and moving onto new process in the pass has always seen huge performance gain).
