Hi everyone, I have a 4,1->5,1 Mac Pro. I just did a CPU upgrade to make it a 12-Core 2.93GHZ. Here are the full specs: - 12-Core 2.93GHZ - macOS 10.12.5 - 32 GB (8x4GB sticks) - nVidia GT640 1GB (flashed by MVC) - 32" BenQ 4K 60hz Monitor (running 1:1 pixels in full 4K (no scaling) - 4 SSD's MX300 512GB SSD as Boot Drive in regular SATA II port MX300 512GB SSD as a Sample Drive in regular SATA II port Transcend 480GB SSD as a Sample Drive in regular SATA II port Samsung 850 EVO 500GB SSD mounted on an OWC Accelsior S as my "fast" Sample Drive I am an audio professional working with orchestral samples so I have different sections of the orchestra (samples) on different SSD's. I use Digital Performer 9 with a virtual Vienna Ensemble Pro server running several instances of Kontakt. So what do you think I should upgrade internally on the Mac? I don't want to pour a ton of money into it, so I'm trying to figure out the best bang for my buck. Here are my possible ideas (with some questions). 1. Upgrade RAM to 1333Mhz 48GB (6x8GB) to make most of the triple channel system. My question is how much of a change do others notice when full utilizing triple-channel? 2. Put in an NVMe SSD and use the driver found on MacVidCards.com. This would be used as a sample drive to improve performance on my projects. 3. Upgrade Graphics Card to something a little better for UI and to help smooth out the 4k experience (I have noticed occasional UI glitches when running 4K). This is not bad right now and I don't really do a lot of graphics work. But I also don't want to spend a lot of money here (max $150). Was thinking of an nVidia 1050 with the Pascal Driver but a little worried about the stability/performance from others' stories. 4. USB 3.1 PCIe Card. Heard mixed things here. I don't want to interfere with my bluetooth. Anyone found a good card for cheap? I also already use a 3TB USB 3.0 Time Machine External HD. 5. Anything else? For those that don't know about the audio software I use, I do a lot of direct from disk reading from the SSD's. My projects use about 20-30GB of RAM and then they read the rest of the audio samples straight from my SSD's. With my CPU upgrade I don't have any issues CPU-wise. But I feel like I could use a faster latency on the SSD's. Thanks for your thoughts!
