Even with the slight reduction in clock speed, would the new 2.8GHz 8 Core machine still run faster than last year's 3GHz 8 Core machine (April 2007) when running Final Cut Studio 2 apps? Assuming apart from the processor, the new machines benefit from faster bus speed and memory speed... I put off buying last year's 8 core because of the hefty price premium. I am now considering which of the new Mac Pros to buy. My main concern is getting smooth real-time previews in Motion 3 and Final Cut Pro 6. I mostly use the HDV codec which is quite processor intensive. Would I see a big difference when running one of the new 3GHz 8 Core Harpertowns (or indeed a 3.2GHz 8 Core) as opposed to a 2.8GHz 8 Core Mac Pro? If the difference going to be noticeable enough in everyday use to justify the extra cost I would go for it. If it's negligible I would save the money. Whichever I choose, I will be putting in at least an extra 4GB of RAM as soon as supply is steady and the prices come down a bit. I don't mind waiting a little longer for non-realtime renders in FCS2 but being able to get smooth response from Motion 3 when creating graphics is important to me as it is hard to get a feel for your animations without smooth motion. Many thanks for your help. Now if Apple can release some new Cinema Displays or drop the price next week, I can put my order in!
