Up until now I have been using a 24" iMac exclusively. Was thinking of upgrading as it is about four years old. Primary use will be Photo/Video work with the emphasis on Photo. Programs used: iPhoto Lightroom 3 Photoshop Elements 9 MS Office Other uses ( games ) come and go as boredom sets in. Well I was on the fence and could go either way, but with the recent ( this morning ) catastrophic death of an older Power Mac ( G4 ) being used by my kids I need to do something ASAP. My concern is PERFORMANCE. My choices are ...... Retail Sale Units ( NO BTO ) Option 1) 15" Macbook Pro / 2.2GHz quad-core Intel Core i7 / AMD Radeon HD 6750M with 1GB GDDR5 Option 2) 27" iMac / 3.1GHz Quad-Core Intel Core i5 / AMD Radeon HD 6970M with 1GB I know going with #1 means I will have to buy a monitor and that would come later. I guess my concerns are which would be better for my needs. The CPU in the iMac is faster, but the CPU in the MBP has hyperthreading. Where can I find some fair benchmark results comparing the two. I'm gonna be buying tomorrow. THANKS !!!!!! .
