Hi, Just about to buy my first iMac for work purposes and I need some help in verifying that the basic iMac will be sufficient for my needs. I'm on a bit of a budget. What do I need it for? Mostly digital imaging, processing of high resolution RAW files, anywhere between 15 and 50mpix. Software I will be using: Photoshop Extended CS5 + Nik Software plugins + various other non-essentials Lightroom CS5 Bridge CS5 Photomatix PTGUI (maybe) Aperture. I'm not worried about hard drive space because of the firewire and thunderbolt connectivity. It should be easy enough to connect another scratch disk or simply back up files to an external drive. I intend on expanding the RAM with Crucial memory to 8gb. Playing about with the basic iMac in the Apple Store seemed smooth enough, however I didn't have access to really high resolution files and composite PSDs to make the machine work. Otherwise I would've tested it myself.
