We currently own a mid 2010 iMac "Core i7" 2.93 27-Inch Quad Core 2.93 GHz Intel "Core i7" I7-870 (Lynnfield) with 4 gb of ram and 1tb hard drive. We use it for photo and video editing mostly. Lately I have been thinking it would be nice to have a laptop that I could take on work trips with me and family vacations for photo editing and general use. The 13" MBP I feel is likely what I want. My question is would that be able to replace my iMac at home as well? I was thinking of getting a regular monitor and docking it up to that with a an external HD for storage when home. Would I notice a significant drop in performance due to going from a discrete graphic card like the Radeon hd 5750 to the built in Intel iris 5100? The benchmarks put the 5100 less then half the capability of the 5750. But will the SSD and 8 gb of ram make up for that?
