Anybody out there have the 3.4Ghz option with a lot of RAM and the 2GB ATI card? I'm thinking of swapping my MacPro for an iMac but I've been doing tests to see how the machines stack up in render times, specifically in FCPX which uses the GPU on output. Does anybody have an iMac of the specs above and FCPX that might be able to run a test for me? PM me if you're able. What I plan on doing is uploading a decent size Prores file for you to download, add a specific number of built in FCPX effects, and render back out to Prores to clock the time.
