So I'm looking to upgrade to a faster Mac but I'm curious about some real world experiences. I currently have a mid-2010 MacBook Pro 2.4 i5 8gb ram. I am using 1080p footage from a Canon T3i and editing in Final Cut Pro X. I find that a 20 minute video typically takes about 4-6 hours to export. Not to mention that during editing it sounds like a jet plane trying to take flight as background rendering does its thing. I'm torn between 3 options. 1. 27" iMac 3.4 i7 which has the 1gb radeon video card. 2. 21.5" iMac 2.8 i7 that only has the 512gb video card. Or 3. Upgrading my current hard drive to SSD or Seagate Hybrid. I know little about how a computer does what it does but I have listed the three options in order of fastest to slowest which also happens to be most expensive to least expensive. So if for example I go with option #1, will my export times be significantly faster than 4-6 hours? And while #2 will be slower, is that a better bang for buck scenario ($500 difference)? How much does the video card ram play into video editing/exporting?
