While I'm pretty well versed in Apple's offerings, I've been waffling over whether to pick up a new iMac for long enough that I figured I'd solicit some outside advice. I'm a freelancer, and as such money is always a bit tight, but my computer aside from my camera's is basically my main tool. Currently I'm plugging away on a 2 year old white macbook - 2.16 ghz and 2gb of RAM, and boy do I make it work. I'm looking to upgrade mainly to shorten my renders and to get myself some decent screen real estate. Part of me wants to go the easy way and get a 24" imac with the best graphics card I can, but I'm worried the performance bump won't be worth it. I know the mac pro's are beasts, but starting at 2500$ without a monitor is pretty steep. Plus if an imac is going to be five or six times faster than my current macbook that would be amazing, even if a Mac Pro might be 15x faster, I'd consider the imac worth it. So I throw my plight to you all to see what advice there is. Typically my workflow is heavy into After Effects, Final Cut, and Photoshop. Usually rendering and color correcting full 1080 HD or 2K res footage or working on very large images. It's not uncommon for me to have 2-3 hours renders for a 30 second clip. (I also realize that the imac screen isn't the best for color correction, but that can be another discussion). Obviously the graphics card would be a big bump from my macbook but I hear that for rendering graphics/footage it won't be much help (as opposed to 3d stuff where it would rock). Any help is appreciated.
