Looking at a 21.5" iMac. I understand the differences between the 3.06 base model at $1,199 and the 3.20 model for $1,499. Intended use is iPhoto and Aperture, Office, etc... And for work, a lot of VMware Fusion time. I don't game, so I know I won't really benefit much with the faster GPU & extra VRAM the more expensive model has. And I don't really need the extra disk space, as I use external drives for most everything. The 3.20 model has the Intel Turbo Boost feature in its CPU. My question is, is that feature worth $300? As I understand it, this feature is aimed at helping applications that can not leverage the multi-cores. Since the apps listed above presumably multi-thread and can leverage the dual-cores, my guess is that I should not really benefit from Turbo Boost? Thoughts?
