The nMP. I have a 4 core base nMP. I run FCPX. The baselines I use are are how many frames per second I can scan Videos. I would guess it is between 60 and 120 frames per second on external raid 5 hd drives. If I look at the issues the nMP people have compared to the problem with the old boxes, I would say the nMP is geared for professionals who want a tool, not a tech toy. I am building a video data base with FCPx I also run Capture One for photos and Dream Weaver for building a web site. I love the thunderbolt performance and have large video storage needs. The biggest issue I have is using compress across multiple machines. The truth is the nMP is hands down the nMP process videos far better then my iMac and an macbook pro. It runs so much cooler, but again, rendering time for the videos is not my concern, I measure the performance in scanning video in frames per second. If one considers the ten year outlook of the video market, consumer, police, educational, it is easy to see there is going to be a huge market for rock solid video data bases, it is easy to understand the market Apple is gearing up for. Their video database technology is pretty amazing. If I look at the technical issues I have had with my nMP, I think Apple just solved a problem.
