Thanks to all of you for helping here. I have a similar, possibly related, situation:

First of all, I have a MacPro 3,1
2 X 2.8 Quad-Core Intel
OS Mavericks 10.9.5
22 Gbs RAM
I’m using a MacVidCards “flashed” GTX 770 4 Gb for the monitors and
an AJA Kona LHE+ for the broadcast monitor.

The sequence, which is just one music track and three checkerboarded video tracks plays back choppy and eventually, Premiere will freeze – you can’t play the sequence, you can’t save, you can’t force quit Premiere. I just have to crash the computer and bring up Premiere again.

Now, just before this, I had installed a Apple Security Update with a build number 13F1066. MacVidCards pointed me to a MacRumors Posting
about this recent Apple Security Update which caused an issue with the drivers for both OS X 10.9 and 10.10. NVIDIA issued a new driver for 10.10 to resolve the issue and MacVidCards figured out a fairly simple fix for 10.9. They said to sure to follow the instruction exactly:

I did this, and it worked, evidently, since then there is a new driver from NIVIDA. I’ll look at that tomorrow.

But, in the meantime, I noticed that my MAC Activity Monitor was showing up around 185% CPU usage for Premiere Pro, when the sequence was playing,
and the Adobe QT32 Server (Not Responding) which was in red, was showing 145% CPU usage when I was exporting the file.

Now I would presume that these should be well under 100% RAM usage was relatively low.

I would think the freezing and stuttering would somehow be related to this?

Any help would be appreciated, and I thank you all for your time in advance.

OK, great. Thanks! Case closed.

So if I upgrade my other computer to 7.2.2 I should be able to open the project on either machine?

Are the newer versions, beyond Premiere Pro CC 7.2.2. stable? Are there any downsides to downloading the newest version?

I have limited memory – 9 Gbs.

Thank you,

Barry

I had not read that Adobe link. Thank you. I think I now have all the information that I need to build this machine.

Thank you for your help.

Thank you, Greg! One question: how much on-board memorywould you recommend for this card?

Barry

[Barry O’brien]

Thank you, Greg. This is my base-line now for set up.

I really appreciate your help.

Thank you! How much memory would this card need? I do pretty straight-forward videos?

Regarding Adobe Premier, What is processed by the on-board memory? Does it work with the Mercury Engine?

Thank you for your advice!

Thank you. As you can see, I am getting suggestions for which video card I should buy. It seems like a number of them will work.

This question still lurks in my mind: now, all these card will work with Premier’s Mercury Engine in speed along processing time?

Do these cares also accelerate trans-coding time when you are done? Or is that handles by the 8 cores of the Mac Pro?

That part I am not clear on…

Barry

[Barry O’brien]

Thank you. 32 Gbs RAM seem to be the consensus.

[Barry O’brien]

Thank you very much for taking the time to answer. This is really helpful!

Now, will this card work with the Mercury Engine in Premier to speed things along?

Regards,

Barry

Thanks for your reply. I really appreciate it. I’ll look right into this card.
