I was just wondering if anyone has upgraded their late 2008 MBP to a 2011 one. Is it that much faster? I'm asking as it may be the time to upgrade. I'd more than likely go for the 15-inch: 2.0 GHz quad-core i7 as the extra .2 GHz doesn't really make that much of a difference for me. I use CS5, FCP, Motion, Compressor and Handbrake on a fairly regular basis, and I have noticed some slowdown in my late 08 MBP (specs in sig). So do I pull the trigger?
