Greetings all, I'm deciding between thefollowing of what to get: 2010-2012 Mac Pro Tower (Grey) (2) 3.46 GHz Westmere Processor 12 Core 64GB Ram GTX 970 Nvidia 4GB Graphics Card 512GB PCIe Flash Storage (4) TB of storage (1TB in each bay) USB C & USB 3.0 PCIe Expansion card (2) Dell P2715Q 27" 4K Monitors Or Late 2015 27" Retina 5K IMac 4.0 GHz Quad Core i7 processor 32GB Ram AMD Radeon R9 M395x 4GB Video Card 512GB Flash Storage 4 TB external Thunderbolt Storage (1) Apple Thunderbolt Display I do photography and work a lot with Photoshop and Lightroom. I also do music production using Ableton, Pro Tools, and Logic Pro. I render video at times but not too much. I know the Mac Pro is a later model but with all the upgrades it looks like it can still hold its own as regards to speed and power. This would cost me $4000. I also know the IMac is newer and the processors are faster and it also looks like it can hold its own in regards to power and speed. This model would cost me about $3200. Money isn't an option. I just wanted to see what your opinions on this are. Thanks in advance.
