I'm considering a future purchase of the D600, but first want to conduct some due diligence.
I use a 27" iMac, with 4GB RAM using Apple OS 10.7.x (.5, I think). I work with D7000 and D700 files, and the speed of post processing in LR4, while not blazing fast, is acceptable. What kind of performance can I expect when post processing D600 files in LR, given that camera's larger file sizes? Will it be necessary for me to upgrade to 8GB right away in order to achieve acceptable performance?
Your machine can handle a 200mp (that's two hundred) file if you are very careful. I know this because I occasionally do this with an older MacBook Pro with 4GB. One sneeze and it falls into a pit, but then again, this is just a little bigger than what you're asking about.
With more normal files (the ones above are generated by a 36" scanner), whether or not you need 8GB is a matter of how much else you run on the system while LR is running. On the other hand, it's probably just easier to upgrade to 8GB and be done with it. It probably doesn't even cost $150, and it will help every time you power the system on.
