Is this iMac going to be used for home or professional use?

Look at the 27 inch screen models as these model iMacs are the only ones where the user can still install their own RAM plus, these models have faster, more powerful i5 and i7 CPUs.

i7 CPUs are best for video work as well as more powerful GPUs, RAM and plenty of hard drive space.

In addition, the 27 inch iMacs have options for more powerful GPUs.

Other 27 inch iMac options are larger standard internal hard drives or larger Fusion Drives ( standard hard drive and Solid State (Flash memory) Drive combination) or complete Solid State Drives which are much faster than conventional hard drives.
