Forget the GTX 900 series they are obsolete, go with the GTX 10 series I love my overclocked GTX 1060 SC like the EVGA 06G-P4-6163-KR and even with my 8-core i7-5960X at 4.5 GHz and the right driver it does a wonderful job for a reasonable price. Here is the Premiere Pro BenchMark (PPBM). on my system
If you want slightly more GPU acceleration here are the results with a pair of overclocked GTX 1060's
Notice the H.264 timeline improvement and the lower divisor for the for the MPE gain. Forget the +/-1 change in thr other scores as Microsoft's clock is on 1 second resolution on the file time stamps
I wish I could get my hands on a GTX 1070 or 1080 to see how they compare to that 10 second time of the two overclocked GTX1060
This was using Windows 10 and CC2017
Thank you for your answer!
At first I was thinking of getting the GTX 1070, but I have been told it could cause a lot more of trouble because it is recent.
You didn't experience any problems of compability or bugs?
Outside of finding the right nVidia drivers, no. You have to understand I am an experimenter with the capability of running three different versions of Operating Systems and everything from Premiere CS6 up to 11.0.1
ANY card, be it ATI or NVidia, can cause problems if the vendor supplied driver is bad
