.. although I had to redo the hack, which was working fine, and still does, with my GTX480
I've also noticed that the GTX 480 hack still works. However, I think that it is a reasonable assumption that if the GTX 480 works as Adobe expects it to, it would have been certified along with the GTX 470.
That may not be a fair assumption. It's entirely possible Adobe hasn't officially added the 480 because they didn't get a chance to finish testing it.
Lacking approval and not working are two entirely different things. The former doesn't necessarily imply the latter.
It might not be a fair assumption and yet could still be a reasonable assumption. There is no way to know, outside of Adobe and other people who might have been invited to participate in testing, if the GTX 480 was, in fact, tested. But one can say, in any case, that a product that hasn't successfully completed testing, or passed the benchmarks that have been established for it, simply "hasn't completed testing".
Regardless of the assumption that I made, the GTX 480 can still "work". Adobe's announcement might simply mean that it has higher expectations before it provides official support and those of us who choose to use the hack use it our own risk. Again, this is nothing but conjecture.
Another "reasonable" assumption is that if Adobe chose to test the GTX 470 and ignore the GTX 480 for now, then Adobe has truly made a "remarkable" decision.
Apart from technical aspects, that can influence whether a card is certified or not, there may be other considerations, because Adobe is a US based publicly traded company, such as http://www.soxlaw.com/
Thanks for your info. Never thought about the possibility of Sarbanes-Oxley playing a role in product support releases.
I hope this gets to you because I cannot find the original post in the forum at this time. If you do get this message, I'd like to get your perspective since it seems that you know a lot about hardware and performance with Premiere. My impression, from something that I rendered last night, is that Premiere 5.02 is possibly rendering faster with 4GB ram than Premiere 5/5.01 did with 8GB RAM. Does this seem possible to you?
The most obvious performance gain in 5.02 is with MPEG2 encoding. There are a number of MPE enhancements that can sometimes improve performance in specific situations with more than 50%. I'm not familiar with all the effects this applies to, but this update is another sizable improvement and well worth the wait IMO. There are of course still things to improve, as there always are with each program, for instance the scale to frame size effect, but give it time and those may be added.
I can't say that overall the performance improvement is such that reducing memory from 8 to 4 GB will still give you a performance benefit, because there are just too many factors in play here, source dimensions, number of tracks, effects applied, VRAM available, etc.
I know this does not answer your question, but it is the best I have at this moment.

But we have to think about it EVERY TIME. It has to be in the front of our minds unfortunately...
I locked the repeat of this thread and will delete it.
Here are the additional comments posted that might be of use on this thread.
In your other thread I replied to your performance question, but it basically boils down to the fact that certification does not improve performance. It is only a guarantee that extensive testing has been done and Adobe feels certain they can provide good support if you have any CUDA related issue with these cards.
Using the hack on non-certified cards does nothing to performance. There is no difference between a hacked 470 or the certified 470. The performance is determined by the efficiency of the algorithms used for CUDA supported functions. In 5.02 there are a lot of enhancements, and a number still missing, but overall there is a sizable performance gain.
Unfortunately there can never be one clear cut answer to your curiosity, because it is a moving target. CUDA has been updated to a newer version, nVidia drivers have had a significant update, the PR code has been updated significantly and CUDA support for a number of effects has been improved or enhanced."
I might have conveyed something that I didn't intend.
I don't mean to suggest that certification necessarily means improved performance. Without knowing how the GTX 470 was tested, I asked my question with the thought that Adobe could have optimized some software after reviewing early test results.
I am guessing here, but I would think that the video card certification process is just a short term thing. At some future point, as the Mercury technology further matures, it might actually become counter-productive, if every possible graphics card were to be certified.
In the meantime, the certification process might mean, in some cases, that a certified video card will either perform or behave better than if it had not been certified."
