My '08 MacPro recently running LR6 works as well as LR5 did on my existing system - not really any delay in editing. However, I would like to change out the older 23" Apple monitor and perhaps a better graphics card compatible with LR6. Currently I have three HD's internal to the MacPro: a 1TB with the OS and LR6 application only; a 3TB for LR Photos, and a 3TB HD as back up for the LR photos. Perhaps it might be desirable to remove these two internal HD's to an external "cage" (not sure whose product) in case I were to move up to the current MacPro "canister" and wish to update the whole system! Or, of course, leaving well enough alone is an option, but the monitor is old and a more current one would help these old eyes.
System:MacPro early '08
Processor 2.8gHZQuad-Core Intel Xeon
Memory 16GB
Graphics Card: NVIDIA GeForece 8800GT w/512MB
Apple 23" Cinema Display 1920 x1200
Pros and cons would be most appreciated, especially re:the graphics card and the moving those internal HD's to an external "cage". Eric Chan's site had some card thoughts on a card, but I am unsure if a better graphics card or newer monitor will work best with this '08 Mac.
Thank you,
