as far as im aware nvidia is skipping the 600 series and going straight to the 700 series for desktop...

leaving the 600 for laptops... personally i wont see any reason to upgrade to the next [strike]gen[/strike] gfx. i was considering the move till i saw the pricing... the top tier single gpu cards are likely to land at around 600bux or 450-500pounds there mid range is likely to be the top end of $400-450/£300-350 and perform no better than a 580 so even for me with a 5870 it wont be worth the outlay on performance grounds.
from what i have seen from both ati and nvidia is a bit of a side ways step on performance yes it has moved forward but not enough... if i can get more performance from 2 way cheaper but older cards buying 1 of these new iterations just doesnt seem worth it. dx11.1? theres still not enough games out that use dx11... nah i want double the performance of my 5870 for the same £300 i payed for it 2 years ago until then i wont even consider upgrading to new arcitecture... i much rather get another 5870 for £150
in answer to the above what do you think i would get for a 250ish 600 series card?.
maybe 10% more performance and a similar drop in power consumption... so 250 will get a 560 now or a 660/760 on the next iteration which will probably perform as well as the current 570 but thats a guess.[/quotemsg
According to that article if its true the 780 is going to be twice as fast as 580 I'm just hoping that the 760 gets the sane oerfirnane as the 580 does at the 300 or less range if not ill probably stick with a 560ti its on sale for 189 at newegg
