[citation][nom]jay2tall[/nom]So basically a GTX580 with 1 SMX disabled? @ $349-399. This card should fly off the shelves, as long as the supplies are there.[/citation]
Agreed, which is why you'll probably see it at $399. This is unfortunate as I'm currently looking for a card but not in a hurry. I'd buy it at $350. At $400, I think I'll wait to see where the 7950 settles out first.
[citation][nom]jay2tall[/nom]The GTX680 overclocks like a dream, so I imagine this will to.[/citation]
Guru3D reports a pretty nice overclock in their guides (though no more than I see out of the HD7970). However, it seems that their overclock is getting pushed back down by dynamic boost.

HardOCP was a little less successful. They find that an overclocked HD7970 makes up significant ground compared to an overclocked GTX680.

In any case, until custom cooling/PCBs are available this appears you can count on decent overclockability, but your mileage may vary beyond that.
[nom]spookyman[/nom]Whens the GTX690 coming out Nvidia? Will it be faster then the 7990 radeon?
It will almost certainly be faster
as long as you exclude compute benchmarks. With the 400 and 500 series, Nvidia had a faster architecture that was also larger, hotter, and consumed more power. This meant they had to seriously dial back the performance to make a dual GPU card fit within the required thermal, power, and price envelopes. Now, they are smaller, cooler, and less power hungry. AMD will run into these limitations first. Given that Nvidia is starting with the faster architecture, I can't see them loosing this one.
There is always a trade-off, however. Nvidia has given up significant compute functionality (I'll spare you the details) in order to gain this gaming performance advantage. While compute is gaining in importance, it isn't yet critical. I'd guess the majority of people in the market for these cards still see compute as a minor secondary consideration to gaming performance. There are those, like myself, who view compute as an important consideration, though.
