Hi guys, I've had two sources of different information about which machine has the speed advantage. 1) http://www.primatelabs.ca/geekbench/mac-benchmarks/ This page says the 2008 8-core (2.8ghz) is faster with a benchmark speed of 9231 vs. the 8273 2009 4-core (2.66ghz) 2) http://www.everymac.com/systems/app...erformance-compared-to-early-2008-models.html This page says "The new [low-end 2.66 GHz] quad-core's score in our overall system performance suite, Speedmark 5, was 16 percent faster than that of the previous 2.8 GHz eight-core Mac Pro. It was also 27 percent faster in our Photoshop tests, and 20 percent faster at Compressor than the older system. . . " So I need you guys to provide a third (or more) opinion perhaps with your own real world findings. I will be running a lot of Photoshop, Final Cut Studio, and I tend to run a lot of these things simultaneously. I'm also planning to use Adobe Premiere and maybe After Effects in the future. I'm hoping to sell my 2.8ghz 8-core for the same price I can buy a used 2.66ghz 4-core (which is likely the only Mac Pro 4,1 in that price range) but only if it's better of course! What do you guys think?
