I am having trouble deciding between purchasing two of nVidia's GTX 480 forming a dual sli setup or a single GTx 680 when it comes out. I am most concerned with getting the best price for the performance. Would two GTX 480's best, performance wise, a GTX 680? They almost certainly would be cheaper, immediate, and will only be available at that price for a limited time. Whilst on the the subject of price, should I wait for the prices to drop when the new Kepler cards surface? That would to me seem like my first choice as it is reasonably sound. However when the sale occurred at NewEgg and TigerDirect last week they went out of stock very soon. Will the GTX 480 be available to purchase when they release the GTX 680? Or will they stop making them beforehand to accrue more cheese by forcing price conscious shoppers to buy the GTX 580. Should I consider buying used? For items like graphics cards I usually buy new as I prefer feeling bummed when an electronic device takes a dive. Used clothes are totally groovy though. Thanks for your time,

I would go for a single GTX 680, because it will be much more power sufficient and will run much more cooler.
And also you will have the option on buying another one in the long run and having 2 GTX 680's in SLI.
GTX 480s suck and the new Nvidias are not out therefore what I am suggesting is just get Radeon everybody's doin it.
Well that's not quite correct. As of the close of February, here's what hit Steam's servers:
NVIDIA GeForce GTX 560 10.25%
NVIDIA GeForce GTX 570 4.37%
ATI Radeon HD 6950 3.83%
NVIDIA GeForce GTX 580 3.76%
ATI Radeon HD 6970 1.85%
NVIDIA GeForce GTX 550 3.02%
As of yet the 79xx series has not made the list.
But as to the OP's question..... SLI'd or CF'd mid range cards will always beat one of the high end cards....and by a substantial margin.
$320 for Two 6870's - 701 fps @ $0.46 per frame
$480 for Two 6950's - 759 fps @ $0.63 per frame
$550 for One 7970 - 675fps @ $0.81 per frame
There are some CF issues with the 79xx series and they couldn't complete the game test suite. It is expected that these will be resolved in the next month or two.
Looking at the other team .....
$420 for Two 560 Ti's - 862 fps @ $0.42 per frame
$500 for One 580 - 616 fps @ $0.81 per frame
$1,000 for Two 580s - 953 fps @ $1.05 per frame
So, as ya can see above ......ya can get 40% more performance outta two mid range cards for less money then one top end card. And adding a 2nd top end card only gives ya 10% more performance than the two mid range cards. The same will likely be true of the 680s and 650's .... will you be willing to pay $1,300 for two 680's at any point in time versus two of the mid ranged cars...... that's paying 2.0 - 2.5 times as much money for a 10% increase in performance ????
