Hi, first post here, hopefully you can help me out. I do a lot of video editing on my 1st gen Mac Pro (2.66ghz). I'm considering buying a new 15" Macbook Pro (3.06ghz) to replace it though, as it is just way more convinient. If I have 8 gigs of ram, which I do currently, what kind of change would I see performance-wise? Would it be an upgrade, downgrade, or about the same? I looked at the benchmarks but they all use different versions of everything so it's really hard to interpret. Thanks for the help!
