Would you update to the latest iMac at this juncture (hypothetically), or would you wait til December and take a look at the new Mac Pro? How fast is your iMac compared to your previous iMac, Thunderbolt not withstanding?
My 'new' iMac is almost a year old, now. It's so much faster than the four-year-old MacPro tower it replaced that I haven't given new hardware a thought since I got it. So I have no real opinion on the matter of a new MacPro vs. new iMac vs. old iMac (because I never did any serious editing on the old iMac).
Be aware that OS X Mavericks doesn't play nicely with Adobe CC, yet. I can make it work, now, but there were some early 'gotchas' that I've had to work around.
