Well, its been a while since I last posted.
I am so glad I made the purchase of a 2012 instead of the new Mac Pro.
So far I have upgraded the Ram to 24gb, upgraded the video card to a Radeon 7950, and installed SSD on the PCIe slot. Future upgrades include more ram, adding another SSD for Raid 0 performance,
and swapping out the optical drive for a BluRay burner (to archive my BluRay collection)
There was a downside. Capture one didn't show a significant improvement, Media Pro, almost no improvement. The rest of my apps, especially Nikon Capture NX2, are a lot peppier.
After seeing the price and specs of the Mac Pro, this seems to be a better solution, money wise. (That is if you want to stay with the Apple OS)
All that being said, I am not a fan of the new Cylinder and its lack of internal expandability. The price point is way too high for a more disposable product.
My setup is by no means future proof, but It still has an upgrade path.
Very happy with the purchase.
