Zotac GTX 570's HDMI resolution is limited to 1920x1200p60

I think its bandwidth related because Intel has the same problem with the HD GPU resulting this error message if you try to add 2560x1440p60 as a custom resolution:

Finally the trick was to add 2560x1440p55. But this does not work with Nvidia (lower fps won't , too). P.S. this trick seems not to work anymore with Windows 8.1:

A dirty way to calculate the bandwith:
3840 x 2160 x 24 = 199 065 600 pixels per second
2560 x 1440 x 60 = 221 184 000 pixels per second
2560 x 1440 x 55 = 202 752 000 pixels per second

As you can see the bandwidth with the reduced framerate is nearly the same than with 4K.

The problem is not with Premiere, its with After Effects.

Yes, it seems After Effects won't work properly due to the incompatible CUDA versions on the latest Maxwell GPUs. I get the Ray Tracing error just like everyone else. I still think the 970 would be the right decisions, it is only a matter of time before Adobe has to update CS6/CC to support Maxwell GPUs.

They will never update the old CS6. They never added the 600 or 700 series cards officially to this version and never explained how to enable these cards. The fixes came through the community.

So the only version that will receive an update is CC. But I will never support the subscription model and I'm not alone by that:

P.S. in this article you will find Adobe's answer that they won't update CS6, too.

Maybe Nvidia will update the BIOS or drivers to make it more compatible to old products, but at the moment it does not look like this step is important for them.

They certainly did officially add support for the 600 and 700 cards for CS6. The 11.0.2 update for After Effects added official support for the Kepler video cards(600/700/Titan series). Though they only officially added the 600 series in the supported card list, but all the 700 and Titan series worked too since they were based on the same architecture. That being said, you are right in that they may not ever release an update to CS6 to support the Maxwell cards, at this point the only people that know is Adobe.

However, I have a feeling that once CC is patched to support Maxwell, the community will pretty quickly figure out a way to get it working with CS6. Especially since it sounds to me like it is just a matter of updating the Optix dll file that AE uses to use CUDA. It may be as simple as copying the dll file from the CC version of AE to the CS6 version. In fact, it sounds like someone in one of the threads you linked earlier already got this working by replacing the optix dll with a development dll released by nVidia. I believe Kepler was actually the same situation. The version of Optix was updated with Kepler, and Adobe had to patch AE to use it properly.

As for Adobe saying they won't update CS6, I don't see that anywhere. Adobe's stance is CS6 won't receive any feature updates, meaning they won't add any new features. However, they will continue to patch and support features that are already there. I would assume that includes CUDA support since it is already in CS6. But, again, it all is up to Adobe. I wouldn't put them past it to not support any new cards and not update AE simple to try to push more people towards the CC subscriptions(which I agree is BS). In that case we have to hope the community figures out a way, but I have a strong feeling they will.
