I'm in the market for a more powerful computer for my AVCHD video rendering and music production. I currently have a 2008 Macbook Pro 2.66ghz core 2 duo with 8GB of ram and 240GB SSD. I was looking at older mac desktops and I was wondering do you guys think a 2008 Mac Pro with dual 2.8ghz Xeon (E5462) quad Processors would be better for my needs or a 2010 IMac quad i5 at 2.8ghz? I've found them both for around the same price and I do like the upgradeability on the Mac Pros. Thanks for your help
