Good to know, thanks Jeff. It's amazing, I got this computer almost two years ago and it's still one of the faster Mac Pros you can build. Good investment at the time. Even then, without a RR card, it's wasn't able to get the job done I was expecting of it.
The physical limit for Ram is 32GB, but I heard you can install up to 64GB with OWC. Is there much of a reason to go from 32gb to 64gb? Will I see a difference?
