The reason why nvidia cards don't flicker with dual displays, is because they run at full power at all times, and thereby screwing up any power saving schemes.

So pick your poison.

You can change the power profile in CCC and have it behave the same way.
 
downclocking fine.

tested with sc2, no improvement or worsened performance as far as I can tell.
sc2 is still a cpu hog as ever.

I don't consider Tweaktown to typically be overly kind when reviewing AMD cards, either. The 6870 gains are very impressive, indeed.

Do you perhaps see the 6970 getting closer the the 580 than the 570 soon? Maybe even match it at 2560x1600?

Seeing as the 6870 is getting closer and closer to surpassing the 5870.
 
^ Nothing specific for EoL 4-series cards. You should only get these if you have an issue related to your current driver.

They probably just don't bother to improve 5 series performance because they are EOL. 6870 should never get close to 5870 unless there's heavy tessellation involved. As a 5870CF owner I'm a little pissed that they gave up on improving 5 series performance. Since 5870 and 6870 are architecturally identical aside from improved tessellator it shouldn't be a big hassle to incorporate those improvement to 5 series. They just don't give a damn about owners of their older cards.
 
The did that because back then 5870 and 5970 were still their High End cards. Cayman was released long after they added MLAA support for 5800 series.

In fact, it looks from the Tweaktown article that not only does 11.4 not help the 5 series, it actually hurts it in some cases. Far Cry 2 is the most extreme example: http://www.tweaktown.com/articles/4046/amd_catalyst_11_4_windows_7_driver_analysis/index7.html. The 5870 went from being much faster than the 6870 to being slower (at lower resolutions), because the 5870 got worse while the 6870 improved. Strange, since this game doesn't involve tesselation, which would be where the 6870 could pull ahead.

What I'd really like to see is a crossfire comparison, as 11.4 was supposed to improve scaling, but there has been an ongoing debate whether these improvements would benefit all cards, or if the 6 series had something unique in the hardware that would allow greater improvement.

I think that this is an underhanded move to persuade owners of previous generation cards to upgrade instead of just adding another card.

Looking at the 5970 in the 6990 review and the review of the "new" 5850/5830 from kitguru. AMD improved crossfire scaling on the 5800 series to match the 6800 series.

MLAA was introduced with the 6800 series on October 2010.

6970 and 6950 were released on 15 of December 2010.

Officially MLAA support for the 5000 series was added on CAT 11.2 on the 2X of February 2011 (although it was possible to use hacked drivers since CAT 10.10a to have MLAA on the 5000 series).
