Is gtx770 and gtx780 compatible with 5.5 adobe master collection?
Welcome to the forums.
Please check the below link for the system requirements regarding Premiere pro for all the versions. Gtx770 and Gtx780, were not included in the supported cards list.
Both the card might work if you apply a CUDA hack in Premiere pro. Please go to the below link to check some more detailsregarding CUDA hacking.
The gtx770 and gtx780 are listed as compatible with Premiere Pro CC on Adobe System requirements information site, does this mean that they are compatible with 5.5 adobe master collection also?
The gtx770 and gtx780 are included in the supported card list only in the Premiere pro CC version. It means they are tested with Premiere pro CC. CS 5.5 does not include this card in the list so if you unstall these cards they will not be detected automatically by Premiere pro CS5.5. You have to apply CUDA hack to make Premiere pro CS5.5 to recognise these cards.
Yes, it is possible that the new updates for NVidia card drivers may turn off the MPE in Premiere pro after you have applied the hack and updated the card. So, you have to check with which update MPE in Premiere pro is deteting the card.
This is because the last released update for CS5.5 came out before the introduction of the GeForce 600-series GPUs. And Adobe usually tends to completely cease updating older software (CS6 is currently one of the few exceptions - and only for critical bug fixes, not to add new support) once the newer version is released. No driver version for the newer GeForce GPUs will ever fix or change that.
So, basically, your CS5.5 is considered "EOL" (End Of Life), in the eyes of Adobe, once CS6 came out in May 2012.
On the other hand, you can force MPE GPU acceleration to be enabled by default in CS5.5 or CS6 by simply deleting or renaming the "cuda_supported_cards.txt" file. Do not simply blank out the contents of the "cuda_supported_cards.txt" file without actually deleting the file; otherwise, the exact opposite would occur: Premiere would become locked to the MPE software-only mode even with a GPU that's officially supported for MPE GPU acceleration in Premiere.
Whether your system is up to it is another matter. Do you have an overclocked i7 hexa core or dual Xeon E5-2687W CPU's and 64 GB RAM and more than 400 MB/s transfer rate on all volumes?
I would add more RAM first before doing any further upgrades with that system. 12GB just isn't enough for modern HD or 4K material.
Also, with that CPU just stick with your current GTX 580. Going with a GTX 770 or 780 would not improve performance sufficiently enough on such a mainstream CPU platform to justify paying the higher prices on either of those GPUs.
Put in a total of at least 16GB, preferably 32GB (the maximum that such a system supports). You would have to replace all of your system's memory modules in order to attain the maximum supported amount of RAM.
