No I don't agree with that statement. On closer inspection the 770 is the same kepler family as the 680, therefore it is tried and tested. But the 770 has a higher memory bandwith and CUDA cores for a start, among other things.

The release of the GeForce GTX 770 is a little bit of a weird one, really this is a GeForce GTX 680 in disguise. Now there's nothing wrong with that as it merely is a refresh of an existing product line. The GTX 680 has been a real powerhouse in performance and to date can keep up in the high-end range of dedicated graphics cards. The reality of course for those that have purchased a GTX 680, there's no reason to upgrade whatsoever. Overall you are looking at a performance differential of 10% in favor of the GTX 770. The GTX 770 is faster thanks to a higher standard clock and memory frequency. But it's the same performance as a slightly tweaked GTX 680. What will be interesting to see is how this GTX 770 is going to cannibalize the GTX 680 sales. So keep a close eye on price development. Now I do not want to cast a negative cloud on the GTX 770 as really, it's a great product to have in your PC.
The GeForce GTX 770 overall is a little weird, as the product tested really is all too familiar. Sure it has different (improved) looks and cooling. But the heart of the GTX 770 is the GTX 680, combined with a small tweak on the baseclock clock frequency and memory it brings in a nice 10% gain in performance. The decisive factor obviously is going to be pricing. So the MSRP pricing for GTX 770 overall is EUR 329.00 excl. VAT, which means roughly 395 EUR / USD depending on your country. And that's quite honestly a very reasonable price, especially when you consider that it is the suggested retail price. Shave off another 15% in about four weeks and that will be the final pricing (roughly). The performance of the GeForce GTX 770 is nothing to complain about, in fact at 1920x1200 this might be the best card for the money if you are looking for some brute horsepower in the high-end segment. Overall definitely recommended if you are on the lookout for nice upgrade over say the GTX 500 series.
Welly welly well due all the new info about the 770 I think i'll wait for a while till i'll see the final pricing over here, and then i'll decide, thanks so much for your help and sharing your opinions and exp you guys. Any new info and point of views will be most welcomed.
So the gtx770 finally is here and it costs a negligible 40$ more than the 680, it's slightly a better card and really worth the price difference like you stated, but and the big but is that the power requirements are 600W psu and my psu is 550W, will it work with my psu? Link
