Hi, my daughter is going to be studying A level moving image at college, using final cut pro x and aperture. We want to get an imac but are computer novices, so would appreciate some advice. We are looking at the above two models, is there much difference in terms of speed between 2.7 and 2.9ghz? We will be getting final cut pro x and aperture installed. And were thinking of increasing memory to 16gb and getting 256gb flash storage (over the 1TB fusion drive) will this be enough to smoothly run the two programmes? or should we get 8gb memory and 512gb flash storage?. The imac will be used for college work, video editing shortish movies, photo editing, internet. The only other difference between the two models is the 2.9 has a NV1DIA Geforce GT780m with 1 GB video memory graphics card. Is this worth having when not into gaming?, will it be beneficial to the final cut pro x? We looked at the imac over the laptop macbook pro, as she is unlikely to need to take the computer to college. And isnt going to university for 3 years. So we figured an imac to be a better buy as spec is greater? Any advice would be greatly appreciated.
