Good questions and comments. But, guru3d and anandtech said that the nvidia settings for the noise reduction have to be adjusted to improve it and ultimately, video quality was slightly better than the ati cards. It could be subjective but all of them were eventually able to get the HD-HQV working with Nvidia's cards.
I understand what you're saying, but why do they give ATi 15, and the rest give them 25, is it the subjective, well we have to give someone a win somewhere because we don't want them to both be 100? The TechReport gives the HD2600 series 100 and specifically mentions issues with the GF8600, then Anand gives them a 100 and specifically mentions Noise reduction, so IMO it means the differences are all in the eye of the beer holder, and close to each other. Considering that the Gf8600 had more time to work on drivers and such, I'd say any cmparsion involving beta nV drivers be given the same understanding that this option to turn on/off noise reduction may be in future drivers too. To me it seems that 25 as a score in that realm instead of the 15 that Anad gave would change the results and reduce the main concern they have. given their history I'm not inclined to note any subjective tests from Anand. I'm personally waiting for an update from Cleeve, and also B3D and FiringSquad. I've enjoyed the thoroughness in the past and I want more information as well as demos of the fifferences, where Anand just doesn't have the built up credabilty and background for this.
Even then, I still cannot conclude which one is best to get.
And to me that's the thing, I think it's very situation dependant. Right now both solutions are relatively young, so I would say focus on the tasks you do (in your case Linux may play a big role) and then buy for that. My only concern is when boiling down conclusions and such, get a little to general, especially since it varies from class to class within the architectures.
Much of it will depend on the operation of the drivers and how well they work.
Yeah, and that's such an ever evolving thing for these relatively new cards, especially in their 'non-gaming' tasks. Considering how long it took ATi and nV to get PureVideo and AVIVO working well the first time around, I think there's still more on offer, and both offer a ton of possabilities for improvement with the programmability of their architectures.
What did it for me was the XP support (since I would like to keep my Audigy2ZS at full capacity, not hobbled in Vista) so I chose based on that and one efficiency (since it's a laptop), but we'll see how things improve, because even since the start of the thread the GF8600 XP situation changed, so it's far from finalized.
I do think though if Linux is a big component of your decision either now or as a future role then nV is likley the way to go. XP/Vista is a toss up, but Linux is a clear choice IMO. Things may change by the time you transition the card, but you can't rely on that kind of thing, currently ATi/AMD has some work to do in that area and there's no guarantee anything will improve.
