For music production is the iMac a better choice for many smaller studio and home studio users? Lets start with the iMac. A 27 i5 iMac with 16 GB of memory, 3 TB Fusion Drive and the 4GB GPU runs $2699.00. You purchase two of these and youll have a master-slave DAW using VE Pro 5 ($270)over ethernet. Total price. about $5400. The quad core Mac Pro is $2900. Youll add two TB Displays for an additional $2000. Then youll add some external storage for at least $800 to equal what the two iMacs offer. I'm leaving out back up storage for now. Total Price $5700. If your software can take advantage of the Mac Pro dual GPUs it looks like a a pretty good horse race between these two configurations. But as far as I know there is very little audio software that does tap the GPU.Apples Logic X will but that is probably mostly for audio recording with some effects. So for right now and the near future those two iMacs together will probably kick but on a Mac Pro. And you have two computers for greater flexibility. Ill still wait for some reviews and tests of the Mac Pro to make my decision though.
