Upgrading 2008 MacPro 3,1 to edit RAW using DaVinci – Advice???

[John Sellars]

Got it. I knew there was a reason I went to 24GB when I got my 6GB GPU 😉

Just want to make sure we’re in the the spirit of the OP here, where the 6D has a max raw resolution of 1840×460 @24fps…

That resolution would likely work ok with 12GB of ram but below that your pushing the performance degradation. Also keep in mind the more cuda cores available in the GPU the exponential increase in the amount of system ram required to use them. If the ram is not available those cuda cores sit idle. This is because cores cannot share cache when processing different threads parallel in the GPU. This makes duplication of Data buffers for GPU processing very common which is why the ram cache exponentially increases.
