Subject: [Leica] OT - those thinking of a 36MP camera.....

I have a Mac Pro with dual quad-core processors. Mine are 2.8ghz. I work
with scanned film, which gives much larger files than a 36mp camera. 16bit
RGB scan of a 35mm neg is 128mb and a 6x6 neg is 470mb. That's with no
editing or layers, which make the files a lot bigger. My machine is FAST.
I have not looked at it to see the % of CPU being used, but I know it runs
filters and stuff extremely fast. Almost instantly on 35mm and in a few
seconds on the giant medium format scans.

My processors are not that much faster than yours, but I do have 12GB of
RAM. I wonder if more RAM would help you, it did speed mine up quite a bit
when I upped it from 4 to 12 GB.
