Help updating an old Mac Pro

I was in the same situation you are.  Mac Pro 2X3 Dual Core.  The first thing I did was max out the memory to 16 GB and add a OWC SSD 320 GB drive.  A significant improvement in Photoshop CS 6 and this allows me to wait until next year when the new Mac Pro is suppose to be out.  I am using a Canon 1DS Mark III and a 1Dx so my files are quite large.
