Is my iMac capable of handling these HD files? Especially raw 1080P files shot at 24P? I'm moving from a SD camera and iMovie to a Canon 7D with a copy of Final Cut Studio. Also, as soon as Apple irons out all of the wrinkles with their 27" i5 and i7 units, I might consider picking up one of these purely as my editing station. In the meantime, I wanted to get anyone's opinion on my tech specs. I purchased my iMac back in October 2007 but the only drawback now is that I'm stuck with DDR2 memory capped at 4GB. I take really good care of my Mac. Very little apps installed, monthly clean ups, only 25GB used out of my 320GB internal HDD and external drive set ups for my HTPC content and TM. One of the reasons why this worries me is because I ran a sample mkv at 1080 and I realized some skipping and stuttering. Plus, when viewing my iStat Pro menus, the processor, all temperatures and memory usage were peaking big time. I can only imagine the toll this would take when rendering these files in FCP. Just some of your experiences and technical know how would be much appreciated. Thank you.
