Would I see much performance degradation going from a 2009 Mac Pro (2.66 GHZ quad, GForce GT120, 12 GB) to a 2012 i7 mini (either 2.3 or 2.6 ghz quad)? The new Mac Pro is really overkill for me and I would like to sell my Mac Pro and reclaim the space it takes up. I don't do anything too intensive. Maybe a little Photoshop CS5 for photography and iMovie for video editing. I would take the hard drive I use for movies and videos I watch and place it in either a USB3 or Thunderbolt enclosure.
