I have a Macbook pro, late 2010 model and I've been having trouble editing DSLR video from my Canon 60D. I use the Adobe Premiere Pro CS5 and during playback on the program monitor, the images don't play smoothly, it stutters, it plays fine for a second or two but after that it stutters, like strobe images then completely stops playing while everything else in the timeline plays normally. Now I've come to understand that Macbook pro is obviously not the best machine when it comes to editing HD DSLR footage for a professional action flick using Action Essentials. So I've decided to upgrade to Mac Pro. But I just have worries that whether it will be super fast, super smooth for editing, and the footage will play effortlessly without any glitch. If so, will it be worht the price and worth buying the present model OR is there an ungraded model coming out soon. Since it's real expensive and I'm just starting out as a professional film editor, I need to make sure I buy something that I can invest in and that is long lasting. So, all you guys please kindly help me answer my queries and convince me that Mac Pro is the one to go. Thanks.
