Could you please sanity check my logic here (i have a tendency to out-think myself occassionally).
I currently use a 20" iMac, "late 2006 model" that is limited to 3GB RAM.
2.16 Intel Core 2 Duo processor
2.5 GB RAM
I use 2 external 1 TB WD drives - one for data, one for backup
This system generally works OK, but it boggs down on large files, and the display is fairly marginal for photos, even when calibrated.
I am thinking about replacing it with a new Mac Mini, which I can configure with 4 GB RAM (an increase of 38%). Processor speed seems to be a wash, as is the graphics speed (I think). This will cost ~$800, most of which I can recoup by selling my iMac to a friend.
And perhaps the biggest advantage is to add a monitor better suited to editing photos (NEC, Lacie, Eizo) for another $850 - $1500. It would also make upgrading to the Mac Pro at some point less painful since I would already own a good monitor.
Does this make sense? I realize that it is probably an incremental improvement, but it is an improvement nonetheless correct? Or am I missing something....
Thanks for the help
