Yep I could say so as I obviously unpacked 6950
No way that I wouldn't try it I guess...I have mixed feelings though. I have yet to see temps above 80C and the noise is nonexistant, I can't hear the card over HAF 922 fans and Zalman CNPS x10 and that's at 840/1325.
MLAA is not good enough. I dont mind the text but nV SSAA or mixed modes are times beter for me, particularly in motion. It's a good idea for midrange cards but not enough for an IQ wh*re.

Fair enough. If you tried it and don't like it then it sounds like a 570 is the way to go. Good luck.

Thanks for you subjective view in motion.

Have to add that MLAA in some games looks better than in the others and is very obvious then. I guess it needs time to mature.
What bothers me more is that I forced SGSSAA to Stalker SoC and in that particular game, nV SGSSAA really shines, I made some close - up comparisions and nV covers every edge at stunning quality. In fact x4SSAA + MLAA on AMD is no match for nV x4 SSAA in SoC. AMD picture just SSAAed is also blurred, that's ofc easy to solve but shame that I need to go 3rd party apps for this.
I'll do some other comparisions, remember that SSAA on 5850 looked great so probably just a one game issue.
Performance is ok and 2gb helps stuttering in Stalkers for example.
That ofc are only quick assumptions from short testing with release drivers made by a very busy man . I want to give that card a chance and try at least one whql driver, flash it ofc and reinstall win 7 to be sure.

In motion is most important for me. It looks v.good but can't hold the IQ from stable image like SSAA.
I like it and probably would find it sufficient if I didn't have a choice like SSAA.
Counting money for a 580 in fact, my 40nm path is 5850> 470> 480> 6950> ??? so 570> 580 in the end would really make me look like a fool
I was able to force AA in Viva Pinata using the STALKER AA compatibility flag (0x0000F0C1). It's something I was using successfully when I had my GTX 280 albeit I was limited to 2xMSAA due to performance hit.
I'll check when I get home but I believe that flag also allows AA to be forced in Call of Juarez: Bound in Blood (I don't think the default profile has an AA flag from memory).
I've also managed to get AA working in Divinity II as well as it uses Gamebryo, the same engine that Oblivion uses. Again I'll check the setting I'm using later on and post the compatibility flag on here (I think it's the STALKER one though).

I wish I knew what the differences were between the flags used for various UE3 based games.
Most UE3 games use 000100C5.
Mass Effect uses 080100C5 - so more or less the same but there's 1 extra bit enabled.
And then a few, like Borderlands and Dark Void, use 00000045.
00000045 seems to have the biggest performance hit of the three.
Right now I'm playing Dark Void with PhysX on high, which for the most part, the GTX 570 is able to handle impressively. With AA off, fps drops no lower than 50 or so when the turbulent smoke effects are displayed. Enabling AA with the default compabitility value results in a pretty big hit though. Regardless of whether I use 2x or 4x AA, FPS will drop down into the mid 30s when the smoke effects are displayed. Obviously whatever rendering hack that AA compatibility value performs hits hard regardless of the level of AA.
I switched to using the Mass Effect value, 080100C5; AA still works and the performance is much better - dropping down no less 40-45fps with smoke. However, I don't know what, if any, draw back is with that. E.g. why didn't nVidia use it in the first place? For example, perhaps using this prevents the proper rendering of some effect that I just haven't noticed that I'm missing yet. So I'm hesitant to use it.

More than likely, I do know for example using the wrong aa flag in Bioshock causes the dynamic shadows to go missing and several other lighting effects are broken, I'm guessing there would be similar problems in MassEffect?

my guess is nvidia doesn't actually play test much of these. just look at medal of honor 2010. they don't even have an official AA flag yet and yet theres one that works in the drivers.
Another example, John woo's stranglehold. the default AA flag they use causes a black screen as soon as you try to froce aa in CP. changing it manually i was able to get AA working. this was a while back though so i can't recall which aa setting i used.
it is certainly posible what your saying is true, but in my experience, visual anomalies were clearly visible right away for me in every u3 engine game that ive used wrong compatibility flags with.
if you do manage to find missing rendering between flags, please report it so we can include it in the OP.

If anyone can test 570/ 580 with Dead Space, please report the performance x4 AA + AO. I can still cancel my 6950 auction and if GFs were insufficient, I would do it and wait for Kepler or something.
Thanks in advance.
Thanks in advance.

I did a lot of playing around and so far I haven't seen any noticeable difference in effects using 00000045 and 000100C5 in Dark Void (decided to stick with the more common UE3 flags instead of Mass Effect's).
However, that said, also upon further testing, it turns out that the performance difference between the two might not be as great as I originally reported. I was doing informal performance monitoring by looking at fps in one specific area while turning the jetpack on/off. Due to the variability in the PhysX smoke effect, it seems the performance is pretty variable anyway, and my informal monitoring of the framerate wasn't accurate enough. I still think the more common UE3 flags result in better performance, but it might be by only 1-2 fps.
I have Dead Space installed right now, but do not have the 266.44 drivers installed. If I get around to installing them, I'll check it out.

Would be great as I'm probably going for 570... please do.

new version of nvidia inspector is out
first post updated, or get it here
it depends on the game, the card and settings used. in borderlands i get 10+fps with 4aa at 1680x1050.
Version 1.9.4.3:
- fixed: reset value does not work in some cases
- fixed: short hex inputs were not recognized correctly
- gpu info refresh on window activate
- updated some setting constants
- added 3rd method for driver detection
- skip shader count detection on non unified shader architectures
- always request elevation for profile settings to reduce confusion why (elevated) settings may missed in the past
- other minor improvements.
Nice to see this usefull utility being updated.

Since Mafia 2 was mentioned in another thread was tweaking and had some fun. With 0x000d02c4, for anti-aliasing compatibility, I was able to enable x4 AA with full scene super-sampled and looks pretty darn nifty when compared to what is offered by default - Performance hit was there but nice to see the quality. Did get AA to work in Ruse as well.
Here is my quick shot of Mafia 2 with x4 multi-sampling and x4 full-scene super-sampled. It offers AA on the textures, alphas and shadows.
