My iMac 2007 is slowly dying, and that's a good thing. Right now I'm running Lightroom 4 on it, with its pathetic 2GB of RAM. I have become pretty serious about photography, and upgraded to a Canon 5D MkIII camera; I also intend to start shooting, color correcting and editing (Adobe Premier) HD video. Other than working in LR4 and Photoshop, I use my desktop for going online, and for running iTunes on; I figure the imaging stuff is the most demanding stuff I'll be doing. I've decided I don't want to wait for the new iMacs - I don't want to be a guinea pig for a new design, and I'm worried about heating issues, and how the monitor will look. I think the time has come for me to take the plunge. Based on another thread, for a monitor I'm looking at the NEC PA271W monitor. How should I configure my Mini? Just get the higher end one and max out all the upgrades? I get the feeling from some of the threads here that what I want to do with it is not all THAT demanding, and that older Minis could've handled it fine. What's worth it (other than the upgrade to 16GB of RAM, which seems a no-brainer) in terms of upgrades for what I want to do? I'd been thinking I'd be spending about $3000 on an enhanced iMac, so with $1000 for the monitor, I have some room with the Mini. Not that I WANT to spend all $3000... Thanks in advance.
